Emergent Universe by Tunneling in a Jordan-Brans-Dicke Theory
arXiv:1808.09291 · doi:10.1140/epjc/s10052-019-6811-7
Abstract
In this work we study an alternative scheme for an Emergent Universe scenario in the context of a Jordan-Brans-Dicke theory, where the universe is initially in a truly static state supported by a scalar field located in a false vacuum. The model presents a classically stable past eternal static state which is broken when, by quantum tunneling, the scalar field decays into a state of true vacuum and the universe begins to evolve following the extended open inflationary scheme.
