Semiclassical Methods in AMO Physics

A combination of classical and quantum ideas is the best way to comprehend and answer many problems in quantum mechanics. Not only semiclassical methods are highly intuitive,  but they are also the only path for solution when exact quantum calculations are unfeasible. We apply semiclassical Van Vleck-Gutzwiller propagator formalism, WKB, and classical trajectory Monte Carlo (CTMC) methods to solve our current and new research problems.
