Thick-wall tunneling in a piecewise linear and quadratic potential
Speaker(s): Pascal Vaudrevange
Abstract: After reviewing the basics of Coleman deLuccia tunneling, especially in the thin-wall limit, I discuss an (almost) exact tunneling solution in a piecewise linear and quadratic potential. A comparison with the exact solution for a piecewise linear potential demonstrates the dependence of the tunnelin... read more

Surprising phenomena in a rich new class of inflationary models
Speaker(s): Pascal Vaudrevange
Abstract: We report on a new class of fast-roll inflationary models. In a part of its parameter space, inflationary perturbations exhibit quite unusual phenomena such as scalar and tensor modes freezing out at widely different times, as well as scalar modes reentering the horizon during inflation. One specif... read more
