*/"Oscillons: Properties and Applications of the Lumps that Wouldn't Die"/*

I will present some properties of oscillons, time-dependent localized 
configurations that are
surprisingly long-lived, examining their existence in an arbitrary 
number of spatial dimensions
and in several models, including the Abelian Higgs model. I will then 
show how the presence
of oscillons after a rapid quench can dramatically speed-up the 
nucleation rate in first order
phase transitions in 2 and 3 spatial dimensions, turning the usual 
exponential suppression of
homogeneous nucleation into a power law.
