de Sitter vacuum; thermal activation
Decay of a de Sitter vacuum may proceed through a static instanton, representing pair creation of critical bubbles separated by a distance comparable to the Hubble radius - a process somewhat analogous to thermal activation in flat space. We compare this with related processes recently discussed in the literature.
