Ab-Initio Molecular Dynamics

Computer simulation methods, such as Monte Carlo or Molecular Dynamics, are very powerful computational techniques that provide detailed and essentially exact information on classical many-body problems. With the advent of ab-initio molecular dynamics, where the forces are computed on-the-fly by accurate electronic structure calculations, the scope of either method has been greatly extended. Th...

Ab initio molecular dynamics calculations of ion hydration free energies.

We apply ab initio molecular dynamics (AIMD) methods in conjunction with the thermodynamic integration or "lambda-path" technique to compute the intrinsic hydration free energies of Li(+), Cl(-), and Ag(+) ions. Using the Perdew-Burke-Ernzerhof functional, adapting methods developed for classical force field applications, and with consistent assumptions about surface potential (phi) contributio...

Ab initio molecular dynamics.

In this chapter, an introduction to ab initio molecular dynamics (AIMD) has been given. Many of the basic concepts, like the Hellman-Feynman forces, the difference between the Car-Parrinello molecular dynamics and AIMD, have been explained. Also a very versatile AIMD code, the CP2K, has been introduced. On the application, the emphasis was on the aqueous systems and chemical reactions. The bioc...

Parallel Ab-initio Molecular Dynamics

The Car-Parrinello ab-initio molecular dynamics method is heavily used in studies of the properties of materials, molecules etc. Our Car-Parrinello code, which is being continuously developed at CAMP, runs on several computer architectures. A parallel version of the program has been developed at CAMP based on message passing, currently using the PVM library. The parallel algorithm is based upon...
