Quantum corrections to the black hole entropy using the brick wall model
Gopinath Guin, Arpita Jana, Sunandan Gangopadhyay
It was suggested by 't Hooft that to avoid the divergence of the free energy or entropy of the probe fields, one has to introduce an infrared (IR) cutoff. This introduction of the…
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…
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…
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…
Renormalization group improved cosmology in the presence of a stiff matter era
Gopinath Guin, Soham Sen, Sunandan Gangopadhyay
In \href{https://link.aps.org/doi/10.1103/PhysRevD.92.103004}{Phys. Rev. D 92 (2015) 103004}, simple analytical solutions of the Friedman equations were obtained for a universe hav…
