Shtanov Y. Braneworld model and evolution of the universe

It is established that the cosmological evolution in the braneworld model with induced gravity in the action for the brane has a number of properties that qualitatively distinguish it from the standard cosmological model. It is shown that, in the process of bosonic particle creation after inflation, of great significance is the effect of parametric resonance in the presence of a quickly oscillating inflaton field. A non-stationary theory of creation of baby universe from the physical vacuum is constructed. The quantum pilot-wave dynamics is generalized to a field-gravitational system such as the universe, and its non-local character is demonstrated.
