 CP2K is a quantum chemistry and solid state physics software package that can perform atomistic
 simulations of solid state, liquid, molecular, periodic, material, crystal, and biological systems.
 CP2K provides a general framework for different modeling methods such as DFT using the mixed
-Gaussian and plane waves approaches GPW and GAPW. Supported theory levels include DFTB, LDA, GGA,
-MP2, RPA, semi-empirical methods (AM1, PM3, PM6, RM1, MNDO, ...), and classical force fields (AMBER,

 dynamics, vibrational analysis, core level spectroscopy, energy minimization, and transition state
 optimization using NEB or dimer method.
