QUIP and quippy documentation
The QUIP package (GitHub) is a
collection of software tools to carry out molecular dynamics
simulations. It implements a variety of interatomic potentials and
tight binding quantum mechanics, and is also able to call external
packages, and serve as plugins to other software such as LAMMPS, CP2K and also
the python framework ASE. Various
hybrid combinations are also supported in the style of QM/MM, with a
particular focus on materials systems such as metals and
semiconductors.
quippy is a Python interface to QUIP that provides deep access to
most of the Fortran types and routines. The quippy interface is principally
maintained by James Kermode.
- Long term support of the package is ensured by:
Noam Bernstein (Naval Research Laboratory)
Gabor Csanyi (University of Cambridge)
James Kermode (University of Warwick)
