One-point holographic correlator in the expanding universe
Souvik Paul, Gopinath Guin, Sunandan Gangopadhyay
In this article, we have calculated the time-dependent thermal one-point function of massive operators within an expanding universe. We employ the Randall-Sundrum II braneworld mod…
New insights on mutual information in the island approach to the Page curve
Anirban Roy Chowdhury, Souvik Paul, Sunandan Gangopadhyay
In this article, we have presented one of the very important observations, regarding the behavior of mutual information of two different sets of subsystems in the after Page time s…
Post-Newtonian analysis of the quantum signatures of gravity
Tuhin Chatterjee, Soham Sen, Sunandan Gangopadhyay
In a recent work \href{https://doi.org/10.1103/PRXQuantum.2.010325}{PRX QUANTUM 2 (2021) 010325}, a new way of investigating quantum gravity signatures using quantum information th…
Effect of non-conformal deformation on the gapped quasi-normal modes and the holographic implications
Ashis Saha, Sunandan Gangopadhyay
The spectral curve of quasinormal modes for a massive real scalar field in the background of a non-conformal black brane geometry has been obtained by utilizing a Frobenius type ne…
Holographic Brownian dynamics of a heavy particle in a boosted thermal plasma background
Anirban Roy Chowdhury, Ashis Saha, Sunandan Gangopadhyay
In this work, we have performed a detailed holographic analysis of the stochastic dynamics of a heavy particle propagating through a strongly coupled plasma moving with a constant…
Gravity mediated entanglement of phonons in Bose-Einstein condensates
Soham Sen, Sunandan Gangopadhyay, Vlatko Vedral
The eigenstates of two test-masses (where each test-mass is placed inside of a harmonic trap) separated by a distance, can get entangled where gravity acts as the mediator of entan…
