Spawning semiclassical wavepackets

Journal of Computational Physics, 2023
The semiclassical (or Hagedorn) wavepackets depending on a fixed set of parameters are an orthonormal L²-basis of generalized coherent states. They have been used to solve numerically the time-dependent Schrödinger equation in its semiclassical formulation, yet their localization property makes them inefficient in case of non-local phenomena such as ...
