超导窄沟道电阻态的分岔现象

The bifurcation phenomena in the resistive state of the narrow superconducting channels

V. V. Baranov, A. G. Balanov, V. V. Kabanov

摘要:

本文在含时Ginzburg-Landau模型的基础上,研究了长度为L/ε =10.88的窄超导沟道的电阻态性质。我们已经证明,含时的金-朗道方程的分歧点导致的通道的电流-电压特性的一些奇异性。我们已经分析估计的平均电压和周期的振荡解决方案的相对较小的电流。我们还找到了系统具有混沌行为的电流范围。

英文摘要:

We have investigated the properties of the resistive state of the narrow superconducting channel of the length L/ξ=10.88 on the basis of the time-dependent Ginzburg-Landau model. We have demonstrated that the bifurcation points of the time-dependent Ginzburg-Landau equations cause a number of singularities of the current-voltage characteristic of the channel. We have analytically estimated the averaged voltage and the period of the oscillating solution for the relatively small currents. We have also found the range of currents where the system possesses the chaotic behavior.
