Ab Initio Molecular Dynamics
Description
CP2K is a program to perform simulations of solid state, liquid, molecular and biological systems. It is especially aimed at massively parallel and linear scaling electronic structure methods and state-of-the-art ab-initio molecular dynamics (AIMD) simulations. CP2K is optimized for the mixed Gaussian and Plane-Waves (GPW) method based on pseudopotentials, but is able to run all-electron or pure plane-wave/Gaussian calculations as well. Features include: Ab-initio Electronic Structure Theory Methods using the QUICKSTEP module: * Density-Functional Theory (DFT) energies and forces
* Hartree-Fock (HF) energies and forces
* Moeller-Plesset 2nd order perturbation theory (MP2) energies and forces
* Random Phase Approximation (RPA) energies
* Gas phase or Periodic boundary conditions (PBC)
* Basis sets include various standard Gaussian-Type Orbitals (GTOs), Pseudo-
potential plane-waves (PW), and a mixed Gaussian and (augmented) plane wave
approach (GPW/GAPW)
* Norm-conserving, seperable Goedecker-Teter-Hutter (GTH) and non-linear core
corrected (NLCC) pseudopotentials, or all-electron calculations
* Local Density Approximation (LDA) XC functionals including SVWN3, SVWN5,
PW92 and PADE
* Gradient-corrected (GGA) XC functionals including BLYP, BP86, PW91, PBE and
HCTH120 as well as the meta-GGA XC functional TPSS
* Hybrid XC functionals with exact Hartree-Fock Exchange (HFX) including
B3LYP, PBE0 and MCY3
* Double-hybrid XC functionals including B2PLYP and B2GPPLYP
* Additional XC functionals via LibXC
* Dispersion corrections via DFT-D2 and DFT-D3 pair-potential models
* Non-local van der Waals corrections for XC functionals including B88-vdW,
PBE-vdW and B97X-D
* DFT+U (Hubbard) correction
* Density-Fitting for DFT via Bloechl or Density Derived Atomic Point Charges
(DDAPC) charges, for HFX via Auxiliary Density Matrix Methods (ADMM) and
for MP2/RPA via Resolution-of-identity (RI)
* Sparse matrix and prescreening techniques for linear-scaling Kohn-Sham (KS)
matrix computation
* Orbital Transformation (OT) or Direct Inversion of the iterative subspace
(DIIS) self-consistent field (SCF) minimizer
* Local Resolution-of-Identity Projector Augmented Wave method (LRIGPW)
* Absolutely Localized Molecular Orbitals SCF (ALMO-SCF) energies for linear
scaling of molecular systems
* Excited states via time-dependent density-functional perturbation theory
(TDDFPT)
Ab-initio Molecular Dynamics:
* Born-Oppenheimer Molecular Dynamics (BOMD)
* Ehrenfest Molecular Dynamics (EMD)
* PS extrapolation of initial wavefunction
* Time-reversible Always Stable Predictor-Corrector (ASPC) integrator
* Approximate Car-Parrinello like Langevin Born-Oppenheimer Molecular Dynamics
(Second-Generation Car-Parrinello Molecular Dynamics (SGCP))
Mixed quantum-classical (QM/MM) simulations:
* Real-space multigrid approach for the evaluation of the Coulomb
interactions between the QM and the MM part

Further Features include:
* Single-point energies, geometry optimizations and frequency calculations

for minimum energy path (MEP) calculations
* Global optimization of geometries
* Solvation via the Self-Consistent Continuum Solvation (SCCS) model
* Semi-Empirical calculations including the AM1, RM1, PM3, MNDO, MNDO-d, PNNL
and PM6 parametrizations, density-functional tight-binding (DFTB) and
self-consistent-polarization tight-binding (SCP-TB), with or without
periodic boundary conditions
* Classical Molecular Dynamics (MD) simulations in microcanonical ensemble
(NVE) or canonical ensmble (NVT) with Nose-Hover and canonical sampling
through velocity rescaling (CSVR) thermostats
* Metadynamics including well-tempered Metadynamics for Free Energy
calculations
* Classical Force-Field (MM) simulations
* Monte-Carlo (MC) KS-DFT simulations
