Backreaction inclusive Schwinger effect in flat and de Sitter spacetimes via a self consistent Maxwell Schrodinger semiclassical dynamics

Shagun Kaushal, Suprit Singh

We employ a self consistent framework to study the backreaction effects of particle creation in the coupled semiclassical dynamics of a quantum complex scalar field and a classical…
