Ionization by an Oscillating Field: Resonances and Photons

Ovidiu Costin, Rodica D. Costin, Joel L. Lebowitz

We describe new exact results for a model of ionization of a bound state, induced by an oscillating potential. In particular we have obtained exact expressions, in the form of read…

Nonperturbative time dependent solution of a simple ionization model

Ovidiu Costin, Rodica D. Costin, Joel L. Lebowitz

We present a non-perturbative solution of the Schrödinger equation iψt​(t,x)=−ψxx​(t,x)−2(1+αsinωt)δ(x)ψ(t,x), written in units in which ℏ=2m=1, describing the ionizat…
