Entropy of matter on the Carroll geometry
Saurav Samanta, Bibhas Ranjan Majhi
Two prescriptions for the construction of Carroll geometries, the expansion of geometric variables near horizon and the expansion of metric with zero limit of the expansion paramet…

Thermal scalar field stress tensor on a two dimensional black hole and its near horizon properties
Saurav Samanta, Bibhas Ranjan Majhi
We calculate the thermal renormalized energy-momentum tensor components of a massless scalar field, leading to trace anomaly, on a dimensional static black hole spacetime.…

A note on entropy of matter in presence of gravity: status of extensivity of entropy
Saurav Samanta, Bibhas Ranjan Majhi
Entropy of matter in a very strong gravity depends on cross-sectional area of the container of the system -- is being further bolstered by calculating entropy of a monoatomic gas k…
