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…
Schwinger Effect in Compact Space
Prasant Samantray, Suprit Singh
We consider a theory of scalar QED on a spatially compact 1+1-dimensional spacetime. By considering a constant electric field pointing down the compact dimension, we compute the qu…
Matter-Geometry entanglement in quantum cosmology
Viqar Husain, Suprit Singh
We present a study of the evolution of entanglement entropy of matter and geometry in quantum cosmology. For a variety of Gaussian initial states and their linear combinations, and…
Semiclassical cosmology with back reaction: the Friedmann-Schrodinger equation and inflation
Viqar Husain, Suprit Singh
We propose and study a semi-classical cosmological system akin to the Newton-Schrödinger equation where matter field evolution is determined by time dependent Schrödinger equation.…
Does quantum gravity relate the constants of nature?
Viqar Husain, Suprit Singh
The central equation of quantum gravity is the Wheeler-DeWitt equation. We give an argument suggesting that exact solutions of this equation give a surface in the space of coupling…
Schwinger Pair Production in Hot Anti-de Sitter Space
Prasant Samantray, Suprit Singh
We consider particle production in dimensional thermal Anti-de Sitter space under the influence of a constant electric field. The vacuum-persistence amplitude is given by a n…
