Proof of Renyi QNEC for free fermions
Pratik Roy
Quantum null energy condition (QNEC) is usually stated as a bound on the expectation value of null components of the stress energy tensor at a point in terms of second null shape v…
Erasure tolerant quantum memory and the quantum null energy condition in holographic systems
Avik Banerjee, Tanay Kibe, Nehal Mittal +2
Investigating principles for storage of quantum information at finite temperature with minimal need for active error correction is an active area of research. We bear upon this que…
Quantum thermodynamics of holographic quenches and bounds on the growth of entanglement from the QNEC
Tanay Kibe, Ayan Mukhopadhyay, Pratik Roy
The quantum null energy condition (QNEC) is a lower bound on the energy-momentum tensor in terms of the variation of the entanglement entropy of a sub-region along a null direction…
Geroch Group Description of Bubbling Geometries
Pratik Roy, Amitabh Virmani
The Riemann-Hilbert approach to studying solutions of supergravity theories allows us to associate spacetime independent monodromy matrices (matrices in the Geroch group) with solu…
Linearized Einstein's Equation around pure BTZ from Entanglement Thermodynamics
Partha Paul, Pratik Roy
It is known that the linearized Einstein's equation around the pure can be obtained from the constraint , known as the first law of entanglement, on…
Oscillating Shells and Oscillating Balls in AdS
Avik Banerjee, Arnab Kundu, Pratik Roy +1
It has recently been reported that certain thin timelike shells undergo oscillatory motion in AdS. In this paper, we compute two-point function of a probe field in the geodesic app…
Hair on non-extremal D1-D5 bound states
Pratik Roy, Yogesh K. Srivastava, Amitabh Virmani
We consider a truncation of type IIB supergravity on four-torus where in addition to the Ramond-Ramond 2-form field, the Ramond-Ramond axion (w) and the NS-NS 2-form field (B) are…
