Mixed state entanglement measures for open string geometry
Souvik Paul, Anirban Roy Chowdhury, Sunandan Gangopadhyay
In the gauge/gravity framework flavor degrees of freedom are introduced to the gauge theory side through the insertion of probe flavor branes in the supergravity background. Sc…
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…
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…
Investigating the role of mutual information in the Page curve for a functional renormalization group improved Schwarzschild black hole
Ashis Saha, Anirban Roy Chowdhury, Sunandan Gangopadhyay
The present work delves into probing the importance of mutual information of relevant subsystems in obtaining the correct time-evolution of fine-grained entropy of Hawking radiatio…
A holographic realization of correlation and mutual information
Ashis Saha, Anirban Roy Chowdhury, Sunandan Gangopadhyay
The status of the inequality existing between mutual information and (normalized) thermal two-point connected correlation function, namely, $I(A:B)\ge\frac{(\expval{\mathcal{O}_{A}…

Stability, quasinormal modes in a charged black hole in perfect fluid dark matter
Anish Das, Anirban Roy Chowdhury, Sunandan Gangopadhyay
In this work, we study time-like and null geodesics in a charged black hole background immersed in perfect fluid dark matter (PFDM). Using the condition for circular geodesics, we…
Mutual information of subsystems and the Page curve for Schwarzschild de-Sitter black hole
Anirban Roy Chowdhury, Ashis Saha, Sunandan Gangopadhyay
In this work, we show that the two proposals associated to the mutual information of matter fields can be given for an eternal Schwarzschild black hole in de-Sitter spacetime. Thes…
The role of mutual information in the Page curve
Anirban Roy Chowdhury, Ashis Saha, Sunandan Gangopadhyay
In this work, we give two proposals regarding the status of connectivity of entanglement wedges and the associated saturation of mutual information. The first proposal has been giv…

Entanglement wedge cross section for noncommutative Yang-Mills theory
Anirban Roy Chowdhury, Ashis Saha, Sunandan Gangopadhyay
The signature of noncommutativity on various measures of entanglement has been observed by considering the holographic dual of noncommutative super Yang-Mills theory. We have follo…
