# Semiclassical propagation of coherent states and wave packets: hidden saddles

@inproceedings{Wang2021SemiclassicalPO, title={Semiclassical propagation of coherent states and wave packets: hidden saddles}, author={Huichao Wang and Steven Tomsovic}, year={2021} }

Semiclassical methods are extremely important in the subjects of wave packet and coherent state dynamics. Unfortunately, these essentially saddle point approximations are considered nearly impossible to carry out in detail for systems with multiple degrees of freedom due to the difficulties of solving the resulting two-point boundary value problems. However, recent developments have extended the applicability to a broader range of systems and circumstances. The most important advances are first… Expand
