Vm. Villalba, Creation of scalar particles in the presence of a constant electric field in an anisotropic cosmological universe - art. no. 127501, PHYS REV D, 6012(12), 1999, pp. 7501
In the present article we analyze the phenomenon of particle creation in a
cosmological anisotropic universe when a:constant electric field is present
. We compute, via the Bogoliubov transformations, the density number of sca
lar particles created. [S0556-2821(99)00724-9].
