Path Integral Formulation of Quantum Tunneling: Numerical Approximation and Application to
... In order to approximate this path integral one would normally attempt to find a path that was stationary with respect to S. Since this path will provide the dominant contribution to the integral one could make an expansion of the action around this path. Further explanation of exactly how this is do ...

This includes n-level quantum systems in the rotating wave function approximation (RWA) and in which each laser couples only close levels. For this kind of systems our reduction is crucial to gi ...
