121st Statistical Mechanics Meeting, Rutgers University, New Jersey, USA
One of the tried and true techniques to ionize electrons from a metal is to shine an intense laser pulse on the metal's surface. In this talk I will discuss a simple model for this process, in which the laser is a classical, time-dependent oscillating field. The electron wavefunction is initially taken to be in a steady state of the system without a field, and, at t=0, the laser is switched on. I will discuss how the system evolves to a periodic regime in which the electrons are in resonance with the exciting field.
