Crossref Mar 1, 2014 · In this paper we have introduced i-PI, a Python interface designed to facilitate including nuclear quantum effects in ab initio path integral molecular dynamics simulations. The code contents are published in the link given in the appendix 1. pyrexMD is a Python package that is mainly designed for research projects which.
