Scalar-tensor gravity from thermodynamic and fluid-gravity perspective
Krishnakanta Bhattacharya, Bibhas Ranjan Majhi
Out of several possible extensions of general relativity, the scalar-tensor theory is the most popular for several reasons. Since the quantum description of gravity is yet to be fo…
The Life and Science of Thanu Padmanabhan
Jasjeet Singh Bagla, Krishnakanta Bhattacharya, Sumanta Chakraborty +21
Thanu Padmanabhan was a renowned Indian theoretical physicist known for his research in general relativity, cosmology, and quantum gravity. In an extraordinary career spanning fort…
Fluid-gravity correspondence in the scalar-tensor theory of gravity: (in)equivalence of Einstein and Jordan frames
Krishnakanta Bhattacharya, Bibhas Ranjan Majhi, Douglas Singleton
The duality of gravitational dynamics (projected on a null hypersurface) and of fluid dynamics is investigated for the scalar tensor (ST) theory of gravity. The description of ST g…
Thermogeometric study of van der Waals like phase transition in black holes: an alternative approach
Krishnakanta Bhattacharya, Bibhas Ranjan Majhi
It is well-known that the non-extremal anti-de-Sitter (AdS) black holes show various van der Waals type criticalities, such as the , , , etc. In these cases,…
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…
Abbott-Deser-Tekin like conserved quantities in Lanczos-Lovelock gravity: beyond Killing diffeomorphisms
Krishnakanta Bhattacharya, Bibhas Ranjan Majhi
We obtain the conserved Abbott-Deser-Tekin (ADT)-{\it like} current for the Lanczos-Lovelock gravity for a diffeomorphism vector, which defines the horizon of a spacetime and, impo…
