Quantum field theory in a de Sitter universe transiting to the radiation stage
Juan R. Salazar, Sujoy K. Modak
We study some physical aspects of quantum field theory in a two stage universe starting from the inflationary de Sitter and transiting into the radiation dominated stage. We look i…
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…
Semiclassical gravity with a conformally covariant field in globally hyperbolic spacetimes
Benito A. Juárez-Aubry, Sujoy K. Modak
We prove that semiclassical gravity in conformally static, globally hyperbolic spacetimes with a massless, conformally coupled Klein-Gordon field is well posed, when viewed as a co…
A novel mechanism for probing the Planck scale
Saurya Das, Sujoy K. Modak
The Planck or the quantum gravity scale, being orders of magnitude greater than the electroweak scale, is often considered inaccessible by current experimental techniques. How…
