The Loss of Quantum Coherence due to Virtual Black Holes. In this paper it is shown how such loss of quantum coherence occurs on a microscopic, elementary particle level. A series of axioms are presented for the asymptotic Green’s Functions for quantum gravity in asymptotically flat space. These axioms are the same as for Quantum Field Theory in flat spa

Nonsingular Model of the Universe with the Quantum-Gravitational de Sitter Stage and its Observatione, but it encounters a fundamental difficulty, namely, the existence of a singularity at some finite moment of time t = 0 in the past. The Friedman solution cannot be analytically continued to the region t < 0 where, strictly speaking, there is no space and no time. So, in the scope of classical gen

Can De Sitter Spacetime be a Final State of the Contracting Universe?d to take into account these non-equilibrium processes by introducing a new additional thermodynamic variable, namely explicit time dependence of all thermodynamic potentials into the thermodynamic relations. It is shown that this trick leads to “softening” of the equation of state. It is demonstrat

Self-Consistent Treatment of Vacuum Quantum Effects in Isotropic Cosmology discovery of the black holes quantum evaporation and the complete analysis of vacuum quantum effects in isotropic Universes. It was often pointed out that quantum theory may yield the resolution of one of the main problems of modern theoretical physics — the problem of gravitational singularities.

Quantum Field Theories with Spontaneous Symmetry Breaking in External Gravitational Fields of Cosmole extrapolated back in time according to the Friedmann expansion law a(t) ~ t. (or a(t) ~ t.). In this way one is able to describe the physical processes in the early Universe at least up to the “hadronic stage” characterized by the temperature T ~ 1 GeV. However, within this theory one has to postu
