Dynamical Baryogenesis in Rainbow Cosmology
Surendra Kumar Gour, Malay K. Nandy
We investigate baryogenesis in the framework of rainbow cosmology employing a complex scalar field with a softly broken global -symmetry. The modified dispersion relation of…

Non-Supersymmetric Baryogenesis from -Breaking Scalar Dynamics
Surendra Kumar Gour, Malay K. Nandy
We present a non-supersymmetric mechanism for baryogenesis driven by the nonlinear dynamics of a complex scalar field with generalized self-interaction potentials that explicitly b…

Refractive index for the mechanical refraction of a relativistic particle
Bikram Keshari Behera, Surendra Kumar Gour, Shyamal Biswas
We have analytically determined the refractive index for the mechanical refraction of a relativistic particle for its all possible speeds. We have critically analysed the importanc…
