Quasiadiabatic analysis for ionization of a particle in a periodically perturbed delta(x) potential.
We study an ionization process for a particle bound by an attractive delta(x) potential of a certain depth defined on a finite lattice under an external periodic force. Ionization coincides with the time when first two time dependent energy eigenvalues get close to each other. We use a slow driving force away from the resonance frequency. We also observe intermittent high frequency oscillation which can be analyzed with two level approximation.
