Abstract
Based on the numerical solution of the non-stationary (time-dependent) Ginzburg–Landau equations, we investigated the evolution of the order parameter of superconducting channels of different length under applied voltage (so-called voltage-driven regime). We calculated the current-voltage characteristics for channels of different lengths and found out the origin of their characteristic disorder oscillations. For very long channels in a certain voltage interval we revealed chaotic dynamics of the order parameter. The collected data allowed us to plot the most complete and detailed phase diagram of the resistive state of the superconducting channel in the voltage-driven regime.
