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…

Validating and Implementing Modified Filinov Phase Filtration in Semiclassical Dynamics
Matthew S. Church, Sergey V. Antipov, Nandini Ananth
The Mixed Quantum-Classical Initial Value Representation (MQC-IVR) is a recently introduced approximate semiclassical (SC) method for the calculation of real-time quantum correlati…
