Signatures of quantum geometry from exponential corrections to the black hole entropy
Soham Sen, Ashis Saha, Sunandan Gangopadhyay
It has been recently shown in [Phys. Rev. Lett. 125 (2020) 041302] that microstate counting carried out for quantum states residing on the horizon of a black hole leads to a correc…
Born-Infeld corrections to holographic transport coefficients with spatially modulated chemical potential
Ankur Srivastav, Sunandan Gangopadhyay, Ashis Saha
In this work, we have analytically computed the holographic transport coefficients for (2 + 1)- dimensional strongly coupled field theories, placed in a spatially modulated chemica…
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…
Shadow of Kottler black hole in the presence of plasma for a co-moving observer
Anish Das, Ashis Saha, Sunandan Gangopadhyay
We consider a spherically symmetric black hole metric in (3+1)-dimensions in presence of a positive cosmological constant . We use a general approach as proposed in \cite{1} to…
Mixed state information theoretic measures in boosted black brane
Anirban Roy Chowdhury, Ashis Saha, Sunandan Gangopadhyay
In this paper, we study various mixed state information theoretic quantities for a boosted black brane geometry. We have considered two setups, namely, a strip-like subsystem taken…
