Baryon-dark matter coincidence in Randall-Sundrum Model
Basabendu Barman, Ashmita Das, Partha Kumar Paul +2
Within the framework of the extra-dimensional Randall-Sundrum set-up, we investigate the freeze-in production of Standard Model (SM) gauge-singlet scalar, fermionic, and massive ve…

Freeze-in production of scalaron dark matter in gravity
Basabendu Barman, Ashmita Das, Rakesh Kumar SivaKumar +1
We demonstrate that the scalaron, a scalar degree of freedom, emerging from the theory of gravity, can account for the observed dark matter (DM) abundance if its mass is aro…

Derivative coupling in horizon brightened acceleration radiation: a quantum optics approach
Ashmita Das, Anjana Krishnan, Soham Sen +1
Horizon Brightened Acceleration Radiation (HBAR) signifies a unique radiation process and provides a promising framework in exploring acceleration radiation in flat/ curved spaceti…
