We use a single-mode squeezed thermal vacuum state formalism and examine the nature of a massive homogeneous scalar field minimally coupled to gravity in the framework of semiclassical gravity in a Bianchi type-I universe. We have obtained an estimate leading solution to the semiclassical Einstein equation for the Bianchi type-I universe showing that each scale factor in its respective direction obeys power-law expansion. The mechanism of nonclassical thermal cosmological particle production is also analyzed in the Bianchi type-I universe. [ABSTRACT FROM AUTHOR] |
