Topics in vacuum decay
… more than one classically stable vacuum, quantum tunneling and thermal jumps make the transition between the vacua possible. The transition happens through a first order phase transition started by nucleation of a bubble of the new vacuum. The outward pressure of the truer vacuum makes the bubble …

A study of superconducting lead-indium alloys subjected to hydrostatic pressure using the electron tunneling technique
… energy gap were also determined.</p> <p>Electron tunneling measurements on Al-Al<sub>2</sub>0<sub>3</sub>—PbIn junctions were made at normal pressures and at various pressures ranging up to approximately 36OO bar. The tunneling measurements rely on the fact that an electron, in tunneling through a …

Exploring the String Landscape: The Dynamics, Statistics, and Cosmology of Parallel Worlds
… Three separate questions are addressed - the tunneling dynamics between these vacua, the statistics of their location in moduli space, and the potential realization of slow-roll inflation in the flux potentials generated in string theory. We find that the tunneling transitions that occur …
