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}…

Information theoretic measures for Lifshitz system

Souvik Paul, Anirban Roy Chowdhury, Ashis Saha +1

In this work, we have studied various mixed state information theoretic quantities for an excited state of Lifshitz spacetime in -dimensions. This geometry is the gravity dual…
