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…
Can a localised quantum system see soft photons?
Sanved Kolekar, Jorma Louko
We ask whether soft photons, defined by asymptotic charges, can have consequences for the outcome of localised quantum processes. We consider a spatially localised two-state system…
The role of Unruh effect in Bremsstrahlung
Kajol Paithankar, Sanved Kolekar
An equivalence is demonstrated, by an explicit first order quantum calculation, between the Minkowski photon emission rate in the inertial frame for an accelerating charge moving o…
Generation of CMB and Cosmological constant via bulk viscosity
Sanved Kolekar, S. Shankaranarayanan, S. M. Chitre
A simple model of uniformly expanding, homogeneous Universe with a bulk viscosity is studied wherein the inflationary density decays due to viscous dissipation during the expansion…
Directional dependence of the Unruh effect for spatially extended detectors
Sanved Kolekar
We analyse the response of a spatially extended direction-dependent local quantum system, a detector, moving on the Rindler trajectory of uniform linear acceleration in Minkowski s…
Rindler horizons in the Schwarzschild spacetime
Kajol Paithankar, Sanved Kolekar
We investigate the past and future Rindler horizons for radial Rindler trajectories in the Schwarzschild spacetime. We assume the Rindler trajectory to be linearly uniformly accele…
