| contents | Systems that feature a scalar field $ϕ$ with a quasi scale invariant potential, metastable at $ϕ=0$, can remain trapped, during cosmic evolution, in the `wrong' vacuum because the process of bubble nucleation to the true vacuum is inefficient. If $ϕ$ carries a conserved charge $Q$, the presence in the system of a non-zero chemical potential for $Q$ offers the possibility of escaping eternal supercooling: when a species decouples from the plasma the balance among the stabilising effect of temperature and the destabilising effect of chemical potential can change in favour of the latter, so that $ϕ$ condenses and triggers the transition to the stable phase. |
