Decay of False Vacuum via Fuzzy Monopole in String Theory

TL;DR

This paper explores how fuzzy monopoles in string theory can catalyze the decay of false vacua, revealing new mechanisms for vacuum instability and topology change in the string landscape.

Contribution

It introduces a novel decay mechanism involving dielectric branes supported by lower energy vacua and discusses topology change via dissolving fundamental strings.

Findings

Fuzzy monopoles can trigger false vacuum decay.

Dielectric branes support false vacua against collapse.

Topology change occurs through dissolving fundamental strings.

Abstract

We investigate dielectric branes in false vacua in Type IIB string theory. The dielectric branes are supported against collapsing by lower energy vacua inside spherical or tube-like branes. We claim that such branes can be seeds for semi-classical (or quantum mechanical) decay of the false vacua, which makes the life-time of the false vacua shorter. Also, we discuss a topology change of a bubble corresponding to the fuzzy monopole triggered by dissolving fundamental strings.
