MOLECULAR DYNAMICS AND QUANTUM MOLECULAR DYNAMICS SIMULATIONS ON PARALLEL ARCHITECTURES

Abstract

Efficient parallel molecular dynamics (MD) algorithm based on the multiple-time-step (MTS) approach is developed. The MTS-MD algorithm is used to study structural correlations in porous silica at densities 2.2 g/cm3 to 1.6 g/cm3. Nature of phonons and effects of hydrostatic pressure in solid C60 is studied using the tight-binding MD method within a unified interaction model which includes intermolecular and intra-molecular interactions.
