Kinetic equations for ultrarelativistic particles in a Robertson-Walker Universe and isotropization of relict radiation by gravitational interactions
Yu. G. Ignat'ev, A. A. Popov
Kinetic equations for ultrarelativistic particles with due account of gravitational interactions with massive particles in the Robertson-Walker universe are obtained. On the basis…
Vacuum polarization of a scalar field in wormhole spacetimes
Arkadii A. Popov, Sergey V. Sushkov
An analitical approximation of for a scalar field in a static spherically symmetric wormhole spacetime is obtained. The scalar field is assumed to be both massive and massl…
Cosmic String Created from Vacuum Fluctuaions
Arkadii Popov
The possibility of the cosmic string creation by the vacuum fluctuations of quantum fields in the self-consistent semiclassical theory of gravity is discussed. We use the approxima…
Spherically Symmetric Perturbation of Ultrarelativistic Fluid in Homogeneous and Isotropic Universe
Yu. Ignat'ev, A. Popov
A solution of the linearized Einstein's equations for a spherically symmetric perturbation of the ultrarelativistic fluid in the homogeneous and isotropic universe is obtained. Con…
