Entropic interpretation of the Hawking-Moss bounce

TL;DR

This paper reexamines the Hawking-Moss transition rate, revealing it is governed by the entropy of de Sitter space, emphasizing a holographic principle applicable to static spacetimes with horizons.

Contribution

It demonstrates that the Euclidean action for the Hawking-Moss transition is fully determined by the horizon entropy, highlighting a holographic aspect of static spacetimes.

Findings

Euclidean action equals the de Sitter horizon entropy

Holographic feature extends to static spacetimes with horizons

Shift vector vanishing relates to entropy contribution

Abstract

We revisit the derivation of the Hawking-Moss transition rate. Using the static coordinates, we show that the Euclidean action is entirely determined by the contribution of the entropy of de Sitter space which is proportional to the surface area of the horizon. This holographic feature is common to any static spacetime with a horizon on which the shift vector vanishes.
