Semi-classical kinetic theory for massive spin-half fermions with leading-order spin effects
Arpan Das, Wojciech Florkowski, Avdhesh Kumar +2
We consider the quantum kinetic-theory description for interacting massive spin-half fermions using the Wigner function formalism. We derive a general kinetic theory description as…

Setting Initial Conditions for Inflation with Reaction-Diffusion Equation
Partha Bagchi, Arpan Das, Shreyansh S. Dave +2
We discuss the issue of setting appropriate initial conditions for inflation. Specifically, we consider natural inflation model and discuss the fine tuning required for setting alm…
