Cosmology with non-minimal scalar field: graceful entrance into inflation
M. V. Libanov, V. A. Rubakov, P. G. Tinyakov
Abstract
We propose a scenario of the beginning of inflation in which the non-vacuum value of the scalar field that drives inflation develops dynamically due to the non-minimal coupling to gravity. In this scenario, inflation emerges as an intermediate stage of the evolution of the Universe, well after the Planck epoch, from a fairly general initial state.
