Local quenches, bulk entanglement entropy and a unitary Page curve
Cesar A. Agón, Sagar F. Lokhande, Juan F. Pedraza
Quantum corrections to the entanglement entropy of matter fields interacting with dynamical gravity have proven to be very important in the study of the black hole information prob…
Probing typical black hole microstates
Jan de Boer, Rik van Breukelen, Sagar F. Lokhande +2
We investigate the possibility that the geometry dual to a typical AdS black hole microstate corresponds to the extended AdS-Schwarzschild geometry, including a region spacelike to…
Spread of Entanglement in Non-Relativistic Theories
Sagar F. Lokhande
We use a simple holographic toy model to study global quantum quenches in strongly-coupled, hyperscaling-violating-Lifshitz quantum field theories using entanglement entropy as a p…
Bulk entanglement entropy in perturbative excited states
Alexandre Belin, Nabil Iqbal, Sagar F. Lokhande
We compute the bulk entanglement entropy across the Ryu-Takayanagi surface for a one-particle state in a scalar field theory in AdS. We work directly within the bulk Hilbert sp…
On the interior geometry of a typical black hole microstate
Jan de Boer, Rik van Breukelen, Sagar F. Lokhande +2
We argue that the region behind the horizon of a one-sided black hole can be probed by an analogue of the double-trace deformation protocol of Gao-Jafferis-Wall. This is achieved v…
Linear response of entanglement entropy from holography
Sagar F. Lokhande, Gerben W. J. Oling, Juan F. Pedraza
For time-independent excited states in conformal field theories, the entanglement entropy of small subsystems satisfies a `first law'-like relation, in which the change in entangle…
