CP2K

CP2K is a freely available (GPL) program, written in Fortran 2003, to perform atomistic simulations of solid state, liquid, molecular and biological systems. It provides a general framework for different methods: density functional theory (DFT) using a mixed Gaussian and plane waves approach (GPW) via LDA, GGA, MP2, or RPA levels of theory, classical pair and many-body potentials, semi-empirical (AM1, PM3, MNDO, MNDOd, PM6) Hamiltonians, and Quantum Mechanics/Molecular Mechanics (QM/MM) hybrid schemes relying on the Gaussian Expansion of the Electrostatic Potential (GEEP).

CP2K provides editor plugins for Vim and Emacs syntax highlighting, along with other tools for input generation and output processing.
