Abstract: Driven systems can exhibit new
behaviors beyond what is possible in equilibrium. We focus on
non-dissipative dynamics of free fermions in disordered systems,
starting with one-dimensional drives with chiral symmetry.
Eigenstates of...
Abstract: In the original CPT theorem one is
restricted to flat space and is unable to make converse statements.
In this talk I will show how we can reformulate the CPT theorem
using a symmetry argument and generalise it to beyond flat space.
This...
Abstract: I will discuss ongoing work on
understanding the algebra of gravitationally-dressed observables
and generalized entropy in generic spacetimes. Special attention
will be paid to spacetimes that underwent an inflationary era in
the far past...
Abstract: I will describe the one-loop
partition function for strings propagating on AdS3 geometries with
NS-NS flux (for generic values of AdS radius in string units). The
essential ingredients that go into this analysis have been
known for a while...
Abstract: In this work we attempt to understand
the analytic structure of amplitudes in theories with broken
Lorentz invariance. To this end, we use as an example a UV complete
model for relativistic superfluids - a complex scalar theory
with...
Abstract: I will describe connections between
ground states of quantum Hall Hamiltonians with
multiple-Landau-level orbitals, whose excitations display
either Abelian or non-Abelian braiding statistics, and
(non-holomorphic) symmetric polynomials...
Abstract: I will describe a double scaled
matrix and tensor integral whose Feynman diagrams can be organized
in a 3d topological expansion which agrees term by term with
partition functions of 3d gravity. The integral is taken over CFT2
data, and...
Abstract: This will be an informal presentation
/ discussion of the basics of holographic theories that live on
Cauchy slices (arXiv:2204.00591), which can be constructed by the
TTbar deformation. Please feel free to bring in questions and
I will...
Abstract: How are infrared divergences related
to the Shapiro time delay in GR? In this pedagogical lecture aimed
at graduate students, we will study the physics of infrared
divergences and their imprint on scattering amplitudes. We will
mostly work...
Abstract: I will review the operator algebraic
formalism that allows to work with quantum spin systems directly in
the thermodynamic limit. I will explain how this formalism can be
used to prove generalized Lieb-Schultz-Mattis theorems that
give...
