Comments on Holographic Finite Density Matter
Andrei Parnachev
1:30pm|Bloomberg Lecture Hall

I will review the low energy excitations and other observables in the strongly interacting finite density states described by holography.

Superselection Sectors in AdS/CFT
Aron Wall
1:30pm|Jadwin Hall, Seminar Room A07
AdS/CFT is a duality relating the degrees of freedom in a D dimensional bulk gravity theory to a (D-1) dimensional theory living on the boundary.
I will argue that in fact the boundary theory contains only a subset of the bulk observables. For each...

The Entanglement Renyi Entropies of Disjoint Intervals in AdS/CFT
Thomas Faulkner
1:30pm|Bloomberg Lecture Hall
I will discuss how to compute Entanglement Renyi Entropies for two dimensional holographic CFTs using AdS_3 handlebody solutions. Some simplifying assumptions are made. The answer I find is consistent with the Ryu-Takayanagi prediction for...

Yet Another Dual Description for N=1 SQCD
Yuji Tachikawa
1:30pm|Bloomberg Lecture Hall
N=1 supersymmetric SU(2) gauge theory with 4 flavors has not only the usual Seiberg dual description, but also the Intriligator-Pouliot dual as an Sp(1) gauge theory, and yet another one found by Csaki, Schmaltz, Skiba and Terning (CSST). We show...

Quantum Computation vs. Firewalls
Daniel Harlow
1:30pm|Bloomberg Lecture Hall
Almheiri, Marolf, Polchinski, and Sully have claimed that unitarity of black hole evaporation is inconsistent with the existence of a smooth horizon. I will argue that computational restrictions prevent the type of thought-experiment which...
