Thermalization in 2d CFTs revisited
Jan de Boer
(Amsterdam U.)
Abstract:
While a lot of work has been done on understanding thermalization in 2d CFTs, several confusing
aspects remain, in particular regarding integrable aspects of 2d CFTs. In this talk I will try to summarize
some of these confusions and how these connect to AdS/CFT and black hole formation. There appears
to be a significant difference between thermalization in low c CFTs versus thermalization in large c CFTs with
gravitational duals.

Black holes, Stokes flows and DC transport at strong coupling
Aristomenis Donos
(Durham U.)
Abstract:
Certain materials, such as the cuprate superconductors and heavy fermion materials exhibit fascinating, yet hard to explain transport properties. Holography provides a consistent framework to examine linear response and in particular transport of strongly coupled matter. I will discuss momentum dissipation in holography and show that DC transport is fixed via a Stokes flow of an "auxiliary fluid" residing on the horizon of black holes.
