论文摘要
在对超过其临界温度远低于其临界温度的超导体中的非平衡情况的描述时，需要Keldysh-Usadel技术（KUT）。但是，非平稳的KUT尚未应用于逼真的电路。此外，固定的kut已应用于无法保证时间独立性的情况。作为此过程的合理性检查，我们诉诸于玩具模型（Ginzburg-Landau模型），涉及涉及非常缓慢的演变的情况。我们发现，即使在这些情况下，忽略了时间变化的明确影响也会导致相位滑动的不准确甚至质性地描述。
In the description of non equilibrium situations in a superconductor at temperatures far below its critical temperature, the Keldysh-Usadel technique (KUT) is required. However, the non-stationary KUT has not been applied to realistic circuits. Moreover, the stationary KUT has been applied in situations where time independence is not guaranteed. As a plausibility check for this procedure, we resort to a toy model (the Ginzburg-Landau model), in situations that involve very slow evolution. We find that, even in these situations, neglecting the explicit influence of time variation leads to inaccurate or even qualitatively wrong description of phase slips.
