DESCRIPTION:Topic: Fractionalization of Charge and Statistics: Anyons in Co
ndensed Matter Systems\n\nSpeakers: Mike Manfra\n\nABSTRACT: A basic tenet
of quantum theory is that all elementary\nparticles are either bosons or
fermions. Ensembles of bosons or\nfermions behave differently due to diffe
rences in their underlying\nquantum statistics. Starting in the late 1970’
s it was theoretically\nconjectured that excitations that are neither boso
ns nor fermions may\nexist under special conditions in two-dimensional int
eracting electron\nsystems. These unusual excitations were dubbed “anyons.
” Anyons\npossess fractional charge and fractional statistics and are expe
cted\nto reside in a variety of topological phases of matter\, however\ndi
rectly probing these properties presents experimental challenges.\nThis le
cture will focus on the development of electronic Fabry-Pérot\ninterferome
ters that resulted in the first direct observation of\nanyonic braiding in
the fractional quantum Hall state at ν=1/3. These\nexperiments have now b
een extended to the more fragile multi-edge-mode\nhierarchy state at ν=2/5
and the technique may provide utility for a\nvariety of condensed matter
systems in which anyons are believed to\nexist.

DESCRIPTION:Topic: Bob in a Black Hole\, or: On Decoherence from Horizons\n
\nSpeakers: Sam Gralla\n\nABSTRACT: Recently it was shown that black holes
impart a fundamental\nrate of decoherence on all nearby quantum superposi
tions [Danielson\,\nSatishchandran\, Wald (DSW) 2022]\, eventually erasing
all quantum\ninformation in their vicinity. The effect can be understood
from\nmeasurement and causality: An observer (Bob) in the black hole shou
ld\nbe able to disturb outside quantum superpositions by measuring their\n
superposed gravitational fields\, but since his actions cannot (by\ncausal
ity) have this effect\, the superpositions must automatically\ndisturb the
mselves! DSW calculated the rate of decoherence up to an\nunknown numeric
al factor for distant observers in Schwarzschild\nspacetime. Working in t
he electromagnetic analog\, we flesh out and\ngeneralize their calculation
to obtain the precise decoherence rate\nfor an observer at an arbitrary l
ocation on the symmetry axis of a\nKerr black hole. We find that the deco
herence vanishes entirely in\nthe extremal limit\, due to the 'Black hole
Meissner effect' screening\nthe Coulomb field from entering the black hole
. This supports the\ncausality picture: Since Bob is unable to measure th
e field of the\noutside superposition\, no decoherence is necessary--and i
ndeed none\noccurs.

DESCRIPTION:Topic: A (non-)Worldsheet Description of Strings in AdS and Flu
x Compactifications\n\nSpeakers: Minjae Cho\n\nABSTRACT: For backgrounds w
ith known exact worldsheet theory\ndescriptions\, ordinary string perturba
tion theory can be employed to\nstudy observables such as spectrum and sca
ttering. However\, the\nmajority of interesting string backgrounds\, inclu
ding AdS and flux\ncompactifications\, lack such descriptions\, posing cha
llenges in\nunderstanding their stringy physics. Since these backgrounds a
re\ntypically described as solutions to low-energy supergravity theory\,\n
having a string-theoretic counterpart to this field theory is\ndesirable.
In this talk\, we discuss how string field theory provides\nsuch a framewo
rk\, along with its limitations. Despite such\nlimitations\, we illustrate
its practical utility in examining physical\nobservables\, particularly i
n examples such as AdS and flux\ncompactifications.

DESCRIPTION:Topic: New perspectives from extreme gravity\n\nSpeakers: Willi
am East\n\nABSTRACT: Complementing the spectacular breakthroughs in gravit
ational\nwave and multi-messenger observations of merging black holes and
\nneutron stars\, advancements in our theoretical understanding and\nmodel
ling of strong gravity are essential to elucidating the nonlinear\ndynamic
s of spacetime. These are motivated by the goal of unlocking\nthe full pot
ential of the observations\, as well as that of deepening\nour understandi
ng of gravitational theory. I will illustrate some of\nthe new physics tha
t might be probed by the dynamics of black holes\nand neutron stars\, and
describe some recent theoretical developments\nthat allow for uncovering n
ovel phenomena and making detailed\npredictions in this regime\, namely te
sting general relativity and\nsignatures of new particles that arise throu
gh black hole instability.\nI will also discuss how such instabilities and
modifications to\ngravity can take black holes to their theoretical extre
me\, and what\nthis teaches us about general relativity.

DESCRIPTION:Topic: High-precision waveforms with the small-mass-ratio limit
\n\nSpeakers: Scott Hughes\n\nABSTRACT: Current gravitational-wave detecto
rs are being upgraded\, and\nplans are developing for future detectors wit
h greater sensitivity\nover broader frequency bands. As instruments impro
ve and develop\,\nmore cycles of sources’ gravitational waveforms will be
measured\nwith greater signal to noise ratio. Such higher fidelity\nmeasu
rements promise to teach us more about their sources and the\nnature of st
rong-field gravity — but only if theoretical modeling of\nthese waves is a
ble to match advances in the detectors. As we\nmeasure waveforms with bet
ter precision\, the likelihood increases that\nsystematic modeling errors
will affect inferences about what we\nmeasure. In this talk\, I will surv
ey recent progress modeling\nwaveforms from small-mass binaries. Such bin
aries\, which exactly\ndescribe important low-frequency gravitational wave
sources\, also\nserve as a limit of the more general binary problem that
can be\nmodeled with very high precision. I will discuss the outstanding
\nprogress that has been made on this problem in recent years\, and how\nw
hat we learn in this limit can be combined with other binary modeling\ntec
hniques to advance modeling for relativistic binaries in general.

will discuss recent developments that identify\nFree Probability -- a ge
neralization of probability theory to\nnon-commuting objects -- as the uni
fying mathematical framework to\ndescribe correlations of chaotic many-bod
y systems. \n\nI will show how the full version of the Eigenstate Thermali
zation\nHypothesis\, the established framework for quantum dynamics that\n
encompasses all the correlations\, can be rationalized and simplified\nusi
ng the language of Free Probability. This approach uncovers\nunexpected co

DESCRIPTION:Topic: Higgs-Confinement Transitions in QCD from Symmetry Prote
cted Topological Phases\n\nSpeakers: Thomas Dumitrescu\n\nABSTRACT: In gau
ge theories with fundamental matter\, such as QCD\,\nthere is typically no
sharp way to distinguish confining and Higgs\nregimes because there are n
o suitable order parameters. It is\nstandard lore that these two regimes
are continuously connected. In\nthis talk I will discuss simple examples i
n which Higgsing and\nconfinement lead to different symmetry protected top
ological (SPT)\nphases\, which are necessarily separated by a phase transi
tion.\nFinally\, I will show that this phenomenon also occurs in QCD at fi
nite\nbaryon density (but zero temperature)\, and comment on possible\nimp
lications for the QCD phase diagram and neutron stars.

DESCRIPTION:Topic: (In)stability of Quasinormal Frequencies of Black Holes
\n\nSpeakers: Claude Warnick\n\nABSTRACT: A perturbed black hole rings dow
n by producing radiation at\ncertain fixed (complex) frequencies - the qua
sinormal frequencies.\nThese frequencies can be identified with the spectr
um of a non-self\nadjoint operator derived from the evolution equation of
the particular\nfield of interest. Thanks to accurate measurements of grav
itational\nwaves\, the quasinormal spectrum of a black hole is increasingl
y an\nobservable quantity. A natural question is whether the quasinormal\n
spectrum is stable to small perturbations of the underlying black hole\nsp
acetime. I will explain how this question is closely connected to\nthe non
-standard nature of the underlying spectral problem\, and\npresent explici
t results that shed light on the problem.

DESCRIPTION:Topic: Gravitational Waves on Kerr Black Holes: Reconstruction
of Linearized Metric Perturbations\n\nSpeakers: Roman Berens\n\nABSTRACT:
The gravitational perturbations of a rotating Kerr black\nhole are notorio
usly complicated\, even at the linear level. In 1973\,\nTeukolsky showed t
hat their physical degrees of freedom are encoded in\ntwo gauge-invariant
Weyl curvature scalars that obey a separable wave\nequation. Determining t
hese scalars is sufficient for many purposes\,\nsuch as the computation of
energy fluxes. However\, some\napplications—such as second-order perturba
tion theory—require the\nreconstruction of metric perturbations. In princi
ple\, this problem was\nsolved long ago\, but in practice\, the solution h
as never been worked\nout explicitly. Here\, we do so by writing down the
metric perturbation\n(in either ingoing or outgoing radiation gauge) that
corresponds to a\ngiven mode of either Weyl scalar. Our formulas make no r
eference to\nthe Hertz potential (an intermediate quantity that plays no\n
fundamental role) and involve only the radial and angular Kerr modes\,\nbu
t not their derivatives\, which can be altogether eliminated using\nthe Te
ukolsky-Starobinsky identities. We expect these analytic results\nto prove
useful in numerical studies and for extending black hole\nperturbation th
eory beyond the linear regime.

DESCRIPTION:Topic: Near-field Cosmology with Stellar Streams\n\nSpeakers: N
ora Shipp\n\nABSTRACT: Stellar streams\, the tidal remnants of globular cl
usters and\ndwarf galaxies orbiting throughout the Milky Way’s halo\, are
some of\nthe most powerful tools in the study of near-field cosmology. In
\nparticular\, they are sensitive probes of the distribution and\nproperti
es of dark matter across multiple scales\, from the smallest\nsubhalos\, t
o the entire dark matter halo\, as well as being excellent\ntracers of the
growth and structure of our Galaxy. Thanks to recent\nlarge photometric\,
astrometric\, and spectroscopic surveys\, the\npopulation of stellar stre
ams around the Milky Way is finally being\nrevealed. In this talk\, I will
present the discovery\,\ncharacterization\, and modeling of the Milky Way
stellar streams. I\nwill also present the first comparative study of stre
am populations in\nobservations and cosmological simulations\, which revea
led\ninconsistencies in orbital parameters\, as well as a wealth of\npoten
tially yet to be detected stellar streams. In addition\, I will\npresent p
lans to use upcoming surveys like the Rubin Observatory LSST\nin order to
discover and analyze tidal structures throughout the Milky\nWay and across
the local Universe. These data will further\nrevolutionize the study of n
ear-field cosmology\, and reveal the\nanswers to critical questions about
the structure and assembly of our\nGalaxy and the nature of dark matter.

DESCRIPTION:Topic: Unraveling the mysteries of our Milky Way black hole Sag
ittarius A*\n\nSpeakers: Sara Issaoun\n\nABSTRACT: In 2022\, the Event Hor
izon Telescope collaboration revealed\nthe first images of the shadow of o
ur Milky Way supermassive black\nhole\, Sagittarius A* (Sgr A*). Since its
detection in the mid-70s\,\nthis bright radio source in the Galactic cent
er has been shrouded in a\nveil of mystery. The Nobel-awarded stellar orbi
ts research in the\nGalactic center pinned down its mass and distance\, sh
owing evidence of\nan extremely compact 4 million-solar-mass object at the
heart of our\nGalaxy. The EHT then provided the first direct evidence tha
t this\nobject is indeed a black hole and resolved its shadow for the firs
t\ntime. In this talk\, I will explain the challenges of imaging Sgr A*\na
nd how these were overcome by the EHT to obtain its latest\nresults. In th
e next decade\, the EHT will have the capability to make\ndetailed high-dy
namic range millimeter and sub-millimeter polarimetric\nmovies of M87\, Sa
gittarius A*\, and other black hole targets –\ntracing the dynamical proce
sses underlying black hole accretion and\njet launching while zooming in o
n stationary horizon-scale features\nthat reveal the imprint of black hole
spin.

DESCRIPTION:Topic: New Dualities Between String Theories and Random Ensembl
es\n\nSpeakers: Victor Rodriguez\n\nABSTRACT: I will introduce two new fam
ilies of critical string\ntheories in two dimensions and explain that\, wh
en viewed as\ntwo-dimensional quantum gravity on the worldsheet\, each is
equivalent\nto a matrix model. The first worldsheet string theory consists
of\nLiouville CFT coupled to timelike Liouville CFT. Its dual\ndouble-sca
led matrix integral has as its leading density of states the\nuniversal Ca
rdy density of primaries in a two-dimensional CFT of\ncentral charge c. Th
e duality holds for any value of the continuous\nparameter c and reduces t
o the JT gravity/matrix integral duality in\nthe large central charge limi
t\, providing a precise stringy\nrealization of JT gravity. The second str
ing theory I will present\nconsists of two Liouville CFT’s with complex ce
ntral charge. At the\nclassical level\, this theory is related to a 2d dil
aton gravity theory\nthat admits solutions with both signs of the cosmolog
ical constant.\nThe dual of this second string theory is a two-matrix mode
l\ncharacterized by a spectral curve with infinitely many branch\npoints.

DESCRIPTION:Topic: A Holographic Trilogy at Large N: The Power\, the Logari

arize recent results on the large N limit of path\nintegrals of 3d SCFTs a
rising on the worldvolume of N M2-branes placed\non compact Euclidean mani
folds. The leading N^3/2 term in the large N\nexpansion of these 'free ene
rgies' receives 1/N\, log(N)\, as well as\nexponentially suppressed correc
tions that can be computed using\nsupersymmetric localization. I will desc
ribe how these corrections\narise in the context of AdS/CFT and will show
that in some instances\nthey can be computed precisely and agree with the
field theory\nresults. I will also discuss the implications of these resul
ts for the\nphysics of AdS black holes and\, more speculatively\, the exis
tence of\nscale separated AdS_4 vacua in string and M-theory.

DESCRIPTION:Topic: Resurgence in Matrix Models and Topological Strings\n\nS
peakers: Maximilian Schwick\n\nABSTRACT: Many recent developments in matri
x models and topological\nstring theory have been driven by resurgence met
hods. \n\nI will introduce basic resurgence concepts in the context of her
mitian\nmatrix models (and their double scaling limits) and demonstrate th
e\nnatural appearance of negative d-branes associated to anti-eigenvalue\n
tunneling (tunneling on the non physical sheet of the spectral curve).\nFu
rthermore I will illustrate how such negative d-branes are a feature\nof t
he t'Hooft limit and necessary for a full non perturbative\nresurgent larg
e N description\, but at the same time are turned off at\nfinite N. \n\nFu
rthermore I will introduce the concept of diagonal framing for\nresurgent
transseries that include negative d-branes. This gives rise\nto an identif
ication of the non perturbative partition functions of\nhermitian matrix m
odels and certain topological strings\, which I will\nillustrate using the
example of (2\,3) minimal strings/H_0 Argyres\nDouglas Theory.

DESCRIPTION:Topic: An Alternative Approach to Solving Two-Dimensional Adjoi
nt QCD\n\nSpeakers: Uwe Trittmann\n\nABSTRACT: The method of e_xhaustively
-symmetrized light-cone\nquantization _(eLCQ) is described. As a continuou
s approach to solving\nquantum bound-state problems\, it exploits the symm
etries of physical\nsystems to generate an optimal set of basis functions.
It has been\nsuccessfully applied to two-dimensional QCD with adjoint fer
mions in\nthe large Nc limit. Corroborating results of discretized approac
hes\,\nit relieves worries that the latter might be flawed when encounteri
ng\nsingular integral kernels. While eLCQ is poised to adequately treat\ns
ingularities in bound-state equations\, it is so far limited to low\nparto
n number. \n\nIn the talk I will highlight the advantages and problems of
the eLCQ\napproach\, and describe forays into finite N and small\ncouplin
g calculations.

DESCRIPTION:Topic: The many uses of emergent perfection in large quantum sy
stems\n\nSpeakers: Joel E. Moore\n\nABSTRACT: An underappreciated aspect o
f quantum mechanics is that\nlarge\, relatively imperfect systems can show
behavior that is as\nprecise and reproducible as anything in nature. The
first example was\nthe observation of superconductivity in 1911\, which re
quired almost\nfifty years and the invention of quantum theory for its the
oretical\nexplanation. A key goal of the second quantum revolution that i
s now\nin progress is to use this and other examples of quantum protection
to\nbuild new computers and sensors. Another goal is to extend our\nabil
ity to create new emergent particles that go beyond the Standard\nModel of
particle physics. This talk explains how these two goals\nare now couple
d: finding materials with new excitations lets us\nrealize new kinds of pr
otected responses\, and quantum computers are\nstarting to help us underst
and even more complex kinds of quantum\nmatter.

theory\, there are limitations in\nour understanding that obscure our pra
ctical use of e.g. quasi-normal\nmode overtone solutions. Towards addressi
ng these limitations\, I’ll\npresent a collection of new results: a radial

Zahra Zahraee\n\nABSTRACT: In this talk we use integrability data to boot
strap\ncorrelation functions of planar maximally supersymmetric Yang- Mill
s\ntheory\, focusing on four-point correlation function of\nstress-tensor.
First\, we start by demonstrating why the conventional\nbootstrap approac

rules that are tailored for this problem as\nthey are only sensitive to s
ingle-traces in the OPE expansion.\nIntegrability enters at this stage and
provides information on the\nspectrum of these operators. Their OPE coeff
icients however remain\nunknown. We then discuss how these sum rules can b
e employed in\nnumerical bootstrap to nonperturbatively bound the OPE coef
ficients.\nWe show\, for the first time\, rigorous bounds for the planar O
PE\ncoefficient of single-trace operators at various t’Hooft couplings\nwe
ll outside the perturbative regime. This talk is based on an\nupcoming pap

escribing a period of exponential\nsuperluminal expansion in the early uni
verse\, is both a proposed\nsolution to the large-scale structure we see i
n our night sky and a\nmystery of which we have little experimental eviden
ce. In this talk\, I\nwill describe two ways to experimentally constrain t
he dynamics of\ninflation : the cosmic microwave background\, and line int
ensity\nmapping. First\, I will describe how the imprint of inflation may
exist\nin the oldest light in the universe\, the cosmic microwave backgrou
nd.\nI will present noise reduction techniques to increase sensitivity fro
m\ncurrent generation large-aperture telescope surveys using data from\nth
e South Pole Telescope\, and propose ways to increase sensitivity to\ninfl
ation by combining data from the large and small telescopes for\nCMB-S4. S
econd\, I will describe a new cosmology technique\, Line\nIntensity Mappin
g (LIM)\, which will be able to probe the middle ages\nof the universe's h
istory to map an evolving 3D cube of time from 11\nbillion years in the pa

unique window into the dynamics of the\ninflationary field(s). I will des
cribe the cameras and analysis\ntechniques I am working on to make some of
the first LIM measurements\nwith the South Pole Telescope Summertime Line
Intensity Mapper and the\nTerahertz Intensity Mapper. These first-gen cam
eras will be deployed\non telescopes as far as the South Pole and as high
as near-space\norbit. These data will be a proof-of-concept that will pro
vide\nprecedent for technology and analysis techniques in this growing fie

DESCRIPTION:Topic: Wormholes and Factorization in Exact Effective Theory\n
\nSpeakers: Sergio Hernandez-Cuenca\n\nABSTRACT: I will discuss the genera
l framework of effective theories\nobtained via exact path integration of
a complete theory over some\nsector of its degrees of freedom.Theories con
structed this way contain\nmulti-integrals which couple fields arbitrarily
far apart. In certain\nsettings these couplings connect path-disconnected
components of the\nspace\, in which case I dub them quantum wormholes.\n
\nAny state the path integral of such an effective theory prepares is\nsho
wn to be a partial trace of a state of the complete theory over the\ninteg
rated-out sector. The resulting reduced density operator is\ngenerally mix
ed due to bra-ket wormholes. An infinite family of\nensembles of pure stat
es of the complete theory giving the same\neffective state is identified.
These allow one to equivalently\ninterpret any effective state as being pr
epared by an ensemble of\ntheories. When computing entropic quantities\, b
ra-ket wormholes give\nrise to replica wormholes. This causes replica path
integrals for the\neffective theory to not factorize even when the underl
ying manifold\ndoes\, as expected from mixing. In contrast\, effective the
ories\nobtained by derivative expansions have no quantum wormholes and\npr
epare pure states. There exist operators in the algebra of effective\ntheo
ries which can distinguish mixed from pure states\, implying a\nbreakdown
of non-exact effective theories for sufficiently complex\nobservables.\n\n
If time allows\, I will also address how this framework unifies and\nprovi
des new insights into much of the phenomena observed in quantum\ngravity\,
including the interplay between wormholes and unitarity\, the\nbreakdown
of bulk effective theory\, the factorization puzzle\, state\nensembles\, t
heory ensembles\, quantum error correction\, and baby\nuniverses.\n\nBased
on 2404.10035.

DESCRIPTION:Topic: Fracture insights into earthquake behavior\n\nSpeakers:
Camilla Cattania\n\nABSTRACT: Earthquakes exhibit complex behavior at all
scales\, from the\nevolution of slip during a single rupture lasting secon
ds to minutes\,\nto the statistics of regional seismicity over years or ce
nturies. The\norigin of complexity in fault behavior has long been debated
: is it a\nreflection of heterogeneity or geometrical complexity of the\nu
nderlying fault system\, or does it arise spontaneously from the\nfriction
al laws that govern fault slip?\n\nIn this talk\, I will present several c
ase studies supporting the view\nthat complex earthquake behavior can aris
e even on very simple fault\ngeometries\, as a consequence of stress gradi
ents and\nvelocity-dependent friction. In each case\, complexity is predic
ted by\nsimple fracture mechanics arguments\, which are validated against
\nnumerical simulations of earthquake cycles with rate-state dependent\nfr
iction.\n\nDuring the interseismic period\, fault slip is characterized by
patches\nof localized creep (or slow slip\, with a sliding velocity ≲ mm/
yr)\,\nnext to locked areas (near-zero sliding velocity). The growth of cr
eep\npatches is described by an energy balance criterion\, in which stress
es\nfrom tectonic loading are balanced by frictional changes within\nslipp
ing cracks. Eventually\, dynamic rupture initiates\, and crack\npropagatio
n is controlled by a balance between the stress intensity\nfactor and a ve
locity-dependent fracture toughness. I apply these\nideas to describe the
seismic cycle on a uniform fault loaded by\nend-point displacement (repres
enting creep at constant velocity on an\nadjacent fault section)\, and dem
onstrate that the stress gradient due\nto loading results in a broad range
of earthquake magnitudes\, with a\npower-law distribution consistent with
regional catalogs\, without the\nneed for underlying complexity. Furtherm
ore\, the model predicts that\nthe same fault can experience both earthqua
kes and transient slow\nruptures at different stages of the seismic cycle\
, as a consequence of\nthe stabilizing effect imparted by lateral loading\
; slow transients\nare reminiscent of slow-slip events frequently observed
at the downdip\nend of megathrust and crustal faults. Finally\, I discuss
the\noccurrence of back-propagating fronts within a single earthquake\, a
nd\nargue that this type of complexity is an intrinsic feature of\nlateral
ly propagating ruptures with a velocity-weakening friction\ncoefficient. T
aken together\, these results demonstrate that fracture\nmechanics is a po
werful technique to explain fault behavior across a\nbroad range of spatio
-temporal scales\, and a flexible tool to\ngeneralize numerical results be
yond a specific realization of\nelasto-frictional properties.

DESCRIPTION:Topic: Forming Truncated Accretion Disks\n\nSpeakers: Gibwa Mus
oke\n\nABSTRACT: Black hole X-ray binaries and Active Galactic Nuclei\ntra
nsition through a series of accretion states in a well-defined\norder. Dur
ing a state transition\, the accretion flow changes from a\nhot geometrica
lly thick accretion flow\, emitting a power-law–like\nhard spectrum to a g
eometrically thin\, cool accretion flow\, producing\nblack-body–like soft
spectrum. The hard intermediate accretion state\npresent in the midst of a
state transition is thought to be associated\nwith the presence of both a
hot geometrically thick component\, termed\nthe corona\, and a cool\, geo
metrically thin component of the accretion\nflow. The details concerning t
he geometry of the disk in the hard\nintermediate state are not agreed upo
n and numerous models have been\nproposed: In the “truncated disk” model\,
the accretion flow is\ngeometrically thick and hot close to the black hol
e\, while the outer\nregions of the flow are geometrically thin and cool.
There are many\nopen questions concerning the nature of truncated accretio
n disks- \nWhich mechanisms generate the truncated disk structure? What se
ts the\nradius at which the disk truncates? How is the corona formed and w
hat\nis its geometry? In this talk I present the first high-resolution 3D
\nGeneral Relativistic Magneto-Hydrodynamic (GRMHD) and radiative GRMHD\ns
imulations modelling the self-consistent formation of a truncated\naccreti
on disk around a black hole.

. These\nfeatures are formalized by a fusion product which we define for a
pair\nof defects\, after isolating divergences that capture the effective
\npotential between the defects\, which generalizes the usual Casimir\nene
rgy. We discuss general properties of the corresponding fusion\nalgebra an
d contrast with the more familiar cases that involve\ntopological defects.
We also describe the relation to a different\ndefect setup in the shape o
f a wedge. We provide explicit examples to\nillustrate these properties us
ing line defects and interfaces in the\nWilson-Fisher CFT and the Gross-Ne
veu(-Yukawa) CFT and determine the\ndefect fusion data thereof.
