Abstract
The system of time-dependent Ginzburg-Landau (GL) equations governing the dynamics of a dirty superconductive filament near Tc is solved numerically with the boundary conditions corresponding to a constant voltage between the edges of the filament. It is demonstrated that, while at small values of the length L of the filament only a time-periodic regime exists, a period doubling occurs at larger L. With the subsequent increase of L, several independent frequencies arise, each corresponding to a periodically appearing phase-slip center. For L sufficiently large, the quasiperiodic regime seems to become chaotic. These results are similar to those obtained previously for a model GL equation with a frequency inhomogeneity, and are in contrast with the situation for the same system in the fixed-current regime, where only time-periodic states are known.
