Numerical study of semiclassical initial value methods for dynamics

摘要: We present numerical tests of five related semiclassical techniques for computing time‐dependent wave functions. These methods are based on integral representations the propagator and do not require searches special trajectories satisfying double‐ended boundary conditions. In many respects, computational involved resemble those conventional quasiclassical treatments. Three these result in globally uniform asymptotic approximations to function. One such method, treatment Herman Kluk, is found be capable especially high accuracy rapid convergence.
