Abstract

In the framework of the quasiclassical self-consistent approach we consider a nonminimally coupled scalar field which serves as a source of torsion in an isotropic homogeneous Universe. We obtain a local asymptotic expansion for the propagator of the scalar field and the effective action, taking into account the effects of vacuum polarization and interaction of scalar particles with the self-consistent gravitational field. The leading polarization contributions can be represented in general-covariant form. A simplified cosmological model is constructed which takes into account the interaction.
