Atomic, Molecular, and Optical Physics 63 (4) : 441021-441024. ScholarBank@NUS Repository. | Abstract: | An idea similar to the block approach used to calculate the path integral of a quantum propagator was employed to obtain a general initial value form of the semiclassical propagator. The semiclassical propagator formulation involves only nearby orbit approximation. The simple initial value form of the semiclassical propagator is nonsingular everywhere is efficient for numeric implementation. A generalized formulation is obtained with the block idea. The initial value form maintains the accuracy with a properly specified weight function. | Source Title: | Physical Review A.
