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...
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...
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...
This talk analyzes the present status of sub-GeV thermal dark
matter annihilating through Standard Model mixing. In these
scenarios, the requirement that dark matter be a thermal relic sets
a sharp sensitivity target for terrestrial experiments, and...
I will review some properties of BPS particles in
four-dimensional N=2 field theories. I will emphasize recent
developments and unsolved problems including restrictions on the
charges of BPS particles, ideas about their large charge
degeneracies...
We will discuss various aspects of the manifold of conformal
field theories. Most of the time will be devoted to a review of
older background material. It will allow us to give a unified and
more conceptual treatment of some recent results.
