Probing Evaporating Black Holes with Modular Flow in SYK
Nicolò Bragagnolo, S. Prem Kumar
We study the effect of modular flow on correlation functions of fermions in the Sachdev-Ye-Kitaev (SYK) model coupled weakly to a bath, which we take to be another SYK model. The s…
Roton-phonon excitations in Chern-Simons matter theory at finite density
S. Prem Kumar, Dibakar Roychowdhury, Stanislav Stratiev
We consider SU(N) Chern-Simons theory coupled to a scalar field in the fundamental representation at strictly zero temperature and finite chemical potential for the global U(1)_B p…
Higher rank Wilson loops from a matrix model
Sean A. Hartnoll, S. Prem Kumar
We compute the circular Wilson loop of N=4 SYM theory at large N in the rank k symmetric and antisymmetric tensor representations. Using a quadratic Hermitian matrix model we obtai…
Multiply wound Polyakov loops at strong coupling
Sean A. Hartnoll, S. Prem Kumar
We study the expectation value of a Polyakov-Maldacena loop that wraps the thermal circle k times in strongly coupled N=4 super Yang-Mills theory. This is achieved by considering p…
AdS black holes and thermal Yang-Mills correlators
Sean A. Hartnoll, S. Prem Kumar
We study the real time correlators of scalar glueball operators for Yang-Mills theory at finite temperature in flat space. The analytic structure of the frequency space propagator…
The O(N) model on a squashed S^3 and the Klebanov-Polyakov correspondence
Sean A. Hartnoll, S. Prem Kumar
We solve the O(N) vector model at large N on a squashed three-sphere with a conformal mass term. Using the Klebanov-Polyakov version of the AdS_4/CFT_3 correspondence we match vari…
