Induced energy-momentum tensor of Dirac field in 2D de Sitter QED
Manizheh Botshekananfard, Ehsan Bavarsad
We compute the expectation value of the energy-momentum tensor in the in-vacuum state of the quantized Dirac field coupled to a uniform electric field background on the Poincar$\rm…

Effect of Schwinger pair production on the evolution of the Hubble constant in de~Sitter spacetime
Ehsan Bavarsad, Sang Pyo Kim, Clément Stahl +1
In this proceeding we consider a massive charged scalar field in a uniform electric field background in a de~Sitter spacetime (dS). We compute the in-vacuum expectation value of th…
