Induced energy-momentum tensor of the scalar field in 3D de Sitter QED
Manizheh Botshekananfard, Takahiro Hayashinaka
In this work, we derive the renormalized expectation value of the energy--momentum tensor of a quantized charged scalar field in three-dimensional de Sitter spacetime $\mathrm{dS}_…

Fermionic Schwinger effect and induced current in de Sitter space
Takahiro Hayashinaka, Tomohiro Fujita, Jun'ichi Yokoyama
We explore Schwinger effect of spin 1/2 charged particles with static electric field in 1+3 dimensional de Sitter spacetime. We analytically calculate the vacuum expectation value…
