Abstract

A simple quantum mechanical model is analyzed for which there is no continuous function which solves the classical equations. The transition amplitude is calculated and it is shown that the discontinuous solution can dominate in the semiclassical approximation. The relevance of this observation is commented upon in a field theory context.
