I will consider the case of a CFT deformed by a relevant
perturbation resulting in a mass gap. I will argue that in such a
case, operators of high scaling-dimension can decouple
exponentially quickly from low-energy bound states. This
observation...
We present new results for Renyi entropy in CFT ground states.
In particular, we describe advances in computation across
non-spherical entangling surfaces and for generic Renyi index,
applicable to arbitrary CFTs. These include the first
rigorous...
I’ll describe how to define and compute Euclidean partition
functions of 4d N=1 theories on spaces that look like a circle
times a simple three manifold. These partition functions can be
interpreted as supersymmetric indices: supertraces over the...
