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…
Fluctuation-dissipation in accelerated frames
Ananya Adhikari, Krishnakanta Bhattacharya, Chandramouli Chowdhury +1
An uniformly accelerated (Rindler) observer will detect particles in the Minkowski vacuum, known as Unruh effect. The spectrum is thermal and the temperature is given by that of th…
Fresh look at the scalar-tensor theory of gravity in Jordan and Einstein frames from undiscussed standpoints
Krishnakanta Bhattacharya, Bibhas Ranjan Majhi
We study the scalar-tensor theory of gravity profoundly in the action level as well as in the thermodynamic level. Contrary to the usual description in the literature about the equ…
Thermogeometric description of the van der Waals like phase transition in AdS black holes
Krishnakanta Bhattacharya, Bibhas Ranjan Majhi
It is well known that interpreting the cosmological constant as the pressure, the AdS black holes behave as the van der Waals thermodynamic system. In this case, like a phase trans…
