Numerical analysis of nanograin collision by classical molecular dynamics

Investigation of Melting by Molecular Dynamics Simulation

The melting of a 64 ion microcrystal of KCI was studied by means of a molecular dynamics computer simulation. We used a central pair interaction with an inverse power law repulsion. The thermodynamics, kinetic and structural properties such as melting temperature, latent heat, mean square displacement, diffusion constant, radial distribution function and bond angle distribution are calculated. ...

Quantum - Classical Molecular Dynamics

We study time integration methods for equations of mixed quantum-classical molecular dynamics in which Newtonian equations of motion and Schrr odinger equations are nonlinearly coupled. Such systems exhibit diierent time scales in the classical and the quantum evolution, and the solutions are typically highly oscillatory. The numerical methods use the exponential of the quantum Hamiltonian whos...

Thermal Conductivity of Solid Argon by Classical Molecular Dynamics

Following the Green-Kubo formalism in linear response theory, the lattice thermal conductivity of solid argon is determined by using classical molecular dynamics simulation to calculate the heat current correlation function. Comparing the absolute conductivities obtained using the LennardJones potential with experiments, we find the predicted results to uniformly underestimate the measurements ...
