We discuss the generalized tunneling through a dynamical barrier for a damped and forced oscillator of the Caldirola-Kanai type. The Landau-Zener-like probability transition from the oscillator ground state to the nth energy level is exactly evaluated by using the Wei-Norman algebraic form of the time evolution operator. Considering a specific example, we show that an increase of the friction parameter gamma implies a decrease of the occupation probability.

Abstract

We discuss the generalized tunneling through a dynamical barrier for a damped and forced oscillator of the Caldirola-Kanai type. The Landau-Zener-like probability transition from the oscillator ground state to the nth energy level is exactly evaluated by using the Wei-Norman algebraic form of the time evolution operator. Considering a specific example, we show that an increase of the friction parameter gamma implies a decrease of the occupation probability.
