Abstract

The evolution of spherically symmetric unstable scalar field configura- tions (“bubbles”) is examined for both symmetric (SDWP) and asymmet- ric (ADWP) double-well potentials. Bubbles with initial static energiesE0 ∼< Ecrit, where Ecrit is some critical value, shrink in a time scale deter- mined by their linear dimension, or “radius”. Bubbles with E0 ∼> Ecrit evolve into time-dependent, localized configurations which are very long-lived com- pared to characteristic time-scales in the models examined. The stability of these configurations is investigated and possible applications are briefly discussed.
