Anisotropic universe space-time non-commutativity and scalar particle creation in the presence of a constant electric field
arXiv:1501.00603
Abstract
We study the effect of the non-commutativity on the creation of scalar particles from vacuum in the anisotropic universe space-time. We derive the deformed Klein-Gordon equation up to second order in the non-commutativity parameter using the general modified field equation. Then the canonical method based on Bogoliubov transformation is applied to calculate the probability of particle creation in vacuum and the corresponding number density in the mode. We deduce that the non-commutative space-time introduces a new source of particle creation.
