The recent focus on entanglement entropy in holography has many
motivations, ranging from the applied (e.g. AdS/CMT) to the
foundational (emergence of gravity). For all of these programs it
is important to find examples, where the quantities of...
The Ryu-Takayanagi formula relates the entanglement entropy in a
conformal field theory to the area of a minimal surface in its
holographic dual. I will show that this relation can be inverted to
reconstruct the bulk stress-energy tensor near the...
We study various protected quantities in five dimensional gauge
theories on R^4S^1 with eight supercharges in the presence of
defects. Surface defects can be described by a certain three
dimensional quiver gauge theories on R^2S^1, whose twisted...
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...
