Application of the generalized fourth-order decomposition schemes to perturbed path integral

Abstract

We prove that the perturbed path integral (PPI) is at least fourth-order accurate and can be combined with generalized fourth-order decompositions to further improve the computational efficiency of path integral molecular dynamics by tuning the parameters.

Status: in preparation.
