Late Time Behavior of False Vacuum Decay

The late time behavior of decaying states is examined with regards to its deviation from the usual exponential form of decay. We will look at the origins of this well-established result in quantum mechanics and discuss the issues that arise in a field theory setting. An increase in the survival probability of a metastable state at large times finds applications in the context of cosmology, namely with regards to eternal inflation and the string theory landscape.
