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…
Entanglement Entropy and Complexity of Multicomponent Universe from Holography
Ritam Mahanta, Gopinath Guin, Souvik Paul +1
Recent studies in \cite{Park:2020jio,Paul:2025gpk} have calculated various holographic information-theoretic quantities of the four-dimensional FLRW universe for different matter-d…
Noncommutative -wave holographic superconductors
Souvik Paul, Sunandan Gangopadhyay
In this work, we have studied the effects of noncommutative geometry on the properties of p-wave holographic superconductors with massive vector condensates in the probe limit. We…
Barrow holographic dark energy interacting model in the presence of radiation and matter
Gopinath Guin, Souvik Paul, Sunandan Gangopadhyay
We have studied the effect of dynamical radiation in the interacting barrow holographic dark energy model for a non-flat universe. For both open and closed universes, we have obtai…
Holographic entanglement entropy and complexity for the cosmological braneworld model
Souvik Paul, Gopinath Guin, Sunandan Gangopadhyay
In a recent study \cite{Park:2020jio}, the time-dependent entanglement entropy of the universe undergoing expansion according to various power laws has been analyzed within the fra…
