The magnetic flux penetrating a superconductor is represented as a set of flux lines, interacting with each other through a realistic potential derived from Ginzburg-Landau theory and with a random pinning potential. The effects of temperature are simulated by a stochastic Langevin force. Initial ca

We study a vortex line motion in type-ll superconductors which is driven by vortex line tenston, Lorentz force, pinning force and thermal fluctuations. On the basis of the local stochastic differential equation for the vortex motmn with no torsion approximation, several computer s~mulations are perf
## Abstract Computer simulations of the molecular motion of polymer chains in the presence of a strong nematic field were carried out by the method of Brownian dynamics. Two models were studied: the first model (linear liquid crystal) is a freely jointed chain with rigid bonds, the second model (co
