One-loop effective potential in Kalb-Ramond scalar electrodynamics
Pratik Chattopadhyay, M. J. Neves
In this work, we study the effective potential at one loop for the Kalb-Ramond scalar electrodynamics. The model is based on a complex scalar field coupled to the electromagnetic f…
Celestial self-dual Yang-Mills theory: a new formula and the OPE limit
Pratik Chattopadhyay, Yi-Xiao Tao
Celestial holography is a new way to understand flat-space amplitudes. Self-dual theories, due to their nice properties, are good subjects to study celestial holography. In this pa…
One-loop effective action in chiral Einstein-Cartan gravity
Pratik Chattopadhyay
In chiral Einstein-Cartan gravity, a new gauge fixing procedure is implemented recently, leading to a very economical perturbation expansion of the action. Using this formulation a…
Dark Matter from Evaporating Primordial Black Holes in the Early Universe
Pratik Chattopadhyay, Arnab Chaudhuri, Maxim Yu. Khlopov
Primordial Black Holes (PBH) could dominate in the early universe and, evaporating before Big bang Nucleosynthesis, can provide new freeze in mechanism of dark matter (DM) producti…
