Crystalline phase transitions are usually simulated for small systems ( w 100 atoms) using metadynamics techniques [6] based on the constant pressure Parinello-Rahman Molecular

Molecular dynamics study of thermal diffusion in a binary mixture of alkanes trapped in a slit pore.. Jean Colombani, Guillaume Galliero, Bernard Duguay, Philippe Bopp,

In this work, we combine neutron scattering experiments in a specific mixture of H 2 O and D 2 O (the so-called null water) with ab initio molecular dynamics simulations in order

We conclude from the results that molecular dynamics simulation with explicit solvent is quite capable of treating the dynamics of interfacial water molecules, even though
