The Emergent Universe scheme and Tunneling

We present an alternative scheme for an Emergent Universe scenario, developed previously in $Phys\mathrm{.}Rev\mathrm{.}D\mathbf{86},083524(2012)$, where the universe is initially in a static state supported by a scalar field located in a false vacuum. The universe begins to evolve when, by quantum tunneling, the scalar field decays into a state of true vacuum. The Emergent Universe models are interesting since they provide specific examples of non-singular inflationary universes.
