Resonant laser excitation in a two-level model: a nonlinear Schrödinger equation?
A nonlinear Schrödinger equation for the dynamics of a resonantly driven two-level model including both T(1) and T(2) processes is presented. This equation is novel in that it can account both for the rate of population flow into an energy level and for the destruction of phase information, i.e., it can account for the system's evolution into a mixed quantum state.
