The quantum Early Universe

Open publisher page 1 citations

Abstract

From the viewpoint of the modern cosmological concepts, the de Sitter vacuum is believed to be the inital stage of evolution of the Universe [l, 2]. The de Sitter vacuum decays into expanding matter called the Friedmann world where we live. There arises a question: what was before the de Sitter stage? The Universe is considered to be born from this vacuum by tunnelling through a certain potential barrier from the pre-de-Sitter domain to the de Sitter one [3, 4, 5, 6, 7, 8, 9].
