超导/普通金属结构对微波的非线性共振

Nonlinear Resonance of Superconductor/Normal Metal Structures to Microwaves

摘要:

本文研究了超导体/普通金属交叉结构中普通金属线在外加微波辐射下的微分电导$G=dj/dV$的变化。我们的理论处理是基于准经典格林函数技术的扩散限制。两个限制的情况下被认为是:第一,弱邻近效应和低微波频率的限制,第二,短尺寸(短正常线)和小的照射幅度的限制。

英文摘要:

We study the variation of the differential conductance $G=dj/dV$ of a normal metal wire in a Superconductor/Normal metal heterostructure with a cross geometry under external microwave radiation applied to the superconducting parts. Our theoretical treatment is based on the quasiclassical Green's functions technique in the diffusive limit. Two limiting cases are considered: first, the limit of a weak proximity effect and low microwave frequency, second, the limit of a short dimension (short normal wire) and small irradiation amplitude.
