Emergent scenario in mimetic gravity

The emergent scenario provides a possible way to avoid the big bang singularity by assuming that the universe originates from an Einstein static state. Therefore, an Einstein static universe stable under the perturbations is crucial to a successful implementation of the emergent mechanism. In this paper, we analyze the stability of Einstein static universe against the scalar perturbations in the mimetic theory and find that the stable Einstein static solutions exist under certain conditions in this theory. While for the original mimetic gravity, the Einstein static universe is unstable. Then, we find that the universe can naturally exit from the initial static state and evolve into an inflationary era. Thus, the emergent scenario can be used to resolve the problem of big bang singularity in the mimetic theory.
