Abstract: We present new solutions of vacuum decay in non-Minkowski spacetimes. On a deSitter background, the tunneling between vacuum states with a nonvanishingenergy difference has been considered, whereas in the special case ofdegenerate vacua we extended the treatment to a power-law FRW-universe.Additionally, we dicuss the vacuum decay in static spacetimes. In the case ofMinkowski spacetime, we include interaction with an environmental field andanalyze the effects of decoherence and the quantum-to-classical transition ofthe nucleating bubble.
