摘要

我们研究了一维方井对势中的安德烈耶夫反射。我们讨论了模型的历史。电流-相位关系是松原频率的总和。我们通过分析延续发现了电流是如何从束缚水平和连续水平产生的。我们讨论了方井势能的两种极限情况,即零长井和无限井。该模型在某些情况下是定量有效的,但它构成了理解非均相超导和超流体中广泛问题的基础。

Square-well Model for Superconducting Pair Potential

Square-well Model for Superconducting Pair Potential

We study Andreev reflection in a one-dimensional square-well pair potential. We discuss the history of the model. The current-phase relation is presented as a sum over Matsubara frequencies. How the current arises from bound and continuum levels is found by analytic continuation. We discuss two limiting cases of the square-well potential, the zero-length well and the infinite well. The model is quantitatively valid in some cases but forms the basis for understanding a wide range of problems in inhomogeneous superconductivity and superfluidity.
