Simulation of atomic deposition between MnAs-clusters — •Andreas Rühl and Christian Heiliger — I. Physikalisches Institut, Justus Liebig University Giessen, D-35392, Germany

We successfully implemented a computational algorithm to calculate and simulate a classical many-body system in a given potential. The considered many-body systems consists of a fixed number of particles, which interact within the boundary conditions suiting the deposition problem at hand. To simulate the condensation of the atoms on a substrate, we included the possibility of cooling down the system by means of a renormalisation of the particles' velocities. So far, the observed results show the equilibration of the system after a certain time, meaning for example, that a random velocity distribution from the start configuration becomes a maxwellian velocity distribution. With the help of the so called radial distribution function we were also able to analyse the system after it has been cooled down to see if the particles arrange in a specific structure.
