摘要：
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 calculations have been confined to a one-dimensional model The current-voltage characteristics of the model have been investigated for a range of temperatures and of relative pinning and interaction strengths and a sharp de-pinning transition has been observed.
