Abstract:Quantum escape of a particle via a time-dependent confining potential in a semi-infinite one-dimensional space is discussed. We describe the time-evolution of escape states in terms of scattering states of the quantum open system, and calculate the probability P (t) for a particle to remain in the confined region at time t in the case of a delta-function potential with a time-oscillating magnitude. The probability P (t) decays exponentially in time at early times, then decays as a power later, along with a tim… Show more
