In the Friday seminar last week, Jennifer Lin talked about our
joint work to characterize gravitational effective theories whose
UV completions are dual to CFT’s on the boundary. I will discuss
our attempt at its converse: how to characterize CFT’s...
In effective field theory, causality fixes the signs of certain
interactions. I will describe how these Lorentzian constraints are
encoded in the Euclidean theory, and use the conformal bootstrap to
derive analogous causality constraints in CFT...
I will present results on how positivity properties of relative
entropy in holographic CFT's give rise to energy conditions in
asymptotically AdS spacetimes. This part will be a sequel to Nima
Lashkari’s talk on 11/2. I will also comment on the...
During the first LHC long shutdown, the CMS collaboration
finalised the study of the 8TeV data collected in 2012. Within the
impressive amount of results produced, a few searches for new
physics show a tension with the prediction from the Standard...
We will discuss the issue of UV completion in the context of weakly
coupled theories. For concreteness, we will ask: is it possible to
complete a low-energy 4-particle scattering amplitude into one
which is well-behaved at high-energies, with only...
In this talk I will discuss how to find superconformal blocks
associated to the four point function of half-BPS operators in N=4
SYM in 4 dimensions. I will discuss how to study this problem in
the analytic superspace and I will conclude with some...
Over the last few years it has become clear that there is a deep
connection between quantum entanglement and gravity. I will talk
about two aspects of this connection. The first involves
understanding quantum entanglement from a holographic...
We will discuss the various algebraic structures that appear
when studying supersymmetric operators in SCFTs in various
dimensions and the connections between them.
For example, topics may include relatively standard
constructions such as chiral...
I will present a new area law in General Relativity. This new
area law holds on local analogues of event horizons that have an
independent thermodynamic significance due to the Bousso bound. I
will also discuss a quantum generalization of this more...
I will consider the Renormalization Group flow of Quantum
Electrodynamics in $d=3$ coupled to $N_f$ flavors of fermions. For
$N_f$ smaller than a critical value $N_f^c$, chiral symmetry
breaking is believed to take place. For $N_f > N_f^c$,
the...
