Resumen:
We study the behavior of a quantum particle, trapped in localized potential, when the trappingpotential starts suddenly to move with constant velocity. In one dimension we have reproducedthe results obtained by (Granot and Marchewka 2009 EPL 86 20007), for an attractive deltafunction, using an approach based on a spectral decomposition, rather than on the propagator.We have also considered the cases of Pöschl-Teller and simple harmonic oscillator potentials (inone dimension) and to the hydrogen atom (in three dimensions). In this last case we havecalculated explicitly the leading contribution to the ionization probability for the hydrogen atomdue to a sudden movement.
