In Jordan-Brans-Dicke theory, the Einstein static universe can be made robust against classical perturbations and representative semiclassical tunneling channels by appropriate choices of the JBD potential and model parameters.

abstract
We present an emergent universe scenario making use of a new solution of the Starobinsky model. The solution belongs to a one parameter family of solutions, where the parameter is determined by the number and the species (spin-values) of primordial fields. The general features of the model have also been studied.

Classical and Semiclassical Stability of Emergent Universes in Jordan-Brans-Dicke Theory
In Jordan-Brans-Dicke theory, the Einstein static universe can be made robust against classical perturbations and representative semiclassical tunneling channels by appropriate choices of the JBD potential and model parameters.
