Model and Numerical Simulations

We study numerically the spatial properties of relaxation clusters in a two dimensional sandpile automaton with dynamic rules depending stochastically on a parameter p, which models the eeects of static friction. In the limiting cases p = 1 and p = 0 the model reduces to the critical height model and critical slope model, respectively. At p = p c , a continuous phase transition occurs to the st...

NUMERICAL SIMULATIONS OF THE PHASE TRANSITIONS IN CLUSTERS

We have studied the phase transitions in atomic clusters by molecular dynamics simulation, assuming Lennard-Jones interatomic pair potential. Calculations are performed by DAP parallel computer. The results are analyzed by simulating their orientational distribution plots (dot-plot), and neutron diffraction patterns. It is shown that all the main features of the bulk phase transitions are e...
