Description
We compute Berry's geometric phase contribution to the vacuum decay amplitude for the parametric harmonic oscillator. Path integral methods are employed to set up an effective action whose (almost) adiabatic approximation will enable us to derive an expression for the probability that the ground state remains in the ground state.
