Study of circular geodesics and shadow of rotating charged black hole surrounded by perfect fluid dark matter immersed in plasma
Anish Das, Ashis Saha, Sunandan Gangopadhyay
In this work, we consider a rotating charged black hole surrounded by perfect fluid dark matter. We consider the system to be immersed in non-magnetised, pressureless plasma. First…
Mutual information, islands in black holes and the Page curve
Ashis Saha, Sunandan Gangopadhyay, Jyoti Prasad Saha
The role played by the mutual information of subsystems on the Page curve is explored in this paper. With the total system consisting of the black hole and radiation, together with…
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…
Entropy function from the Einstein boundary term
Anirban Roy Chowdhury, Ashis Saha, Sunandan Gangopadhyay
We show using the entropy function formalism developed by Sen \cite{Sen:2005wa} that the boundary term which arises from the Einstein-Hilbert action is sufficient to yield the Beke…
Holographic study of entanglement and complexity for mixed states
Ashis Saha, Sunandan Gangopadhyay
In this paper, we holographically quantify the entanglement and complexity for mixed states by following the prescription of purification. The bulk theory we consider in this work…
