Refined approach to cellularization: going from Heller's thawed Gaussian approximation to the Herman--Kluk propagator

Sergey V. Antipov, Fabian Kröninger, Jiří J. L. Vaníček

We present a refined cellularization (Filinov filtering) scheme for the semiclassical Herman--Kluk propagator, which employs the inverse Weierstrass transform and optimal scaling o…
