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…
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.…
Role of spin-orbit coupling effects in rare-earth metallic tetra-borides : a first principle study
Ismail Sk, Nandan Pakhira
We have investigated the electronic structure of rare-earth tetraborides, , using first-principle electronic structure methods (DFT) implemented in Quantum Espress…
A general framework to study the extremal phase transition of black holes
Krishnakanta Bhattacharya, Sumit Dey, Bibhas Ranjan Majhi +1
We investigate the universality of some features for the extremal phase transition of black holes and unify all the approaches which have been applied in different spacetimes. Unli…
Van der Waals criticality in AdS black holes: a phenomenological study
Krishnakanta Bhattacharya, Bibhas Ranjan Majhi, Saurav Samanta
AdS black holes exhibit van der Waals type phase transition. In the {\it extended} phase-space formalism, the critical exponents for any spacetime metric are identical to the stand…
Entropy corresponding to the interior of a Schwarzschild black hole
Bibhas Ranjan Majhi, Saurav Samanta
Interior volume within the horizon of a black hole is a non-trivial concept which turns out to be very important to explain several issues in the context of quantum nature of black…
