I will present recent results on the computation of finite N
corrections in supergravity in the context of AdS2/CFT1 and
AdS4/ABJM holography. I will show how to use localisation in
supergravity to compute all perturbative and nonperturbative
charge...
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...
