微带线中点约瑟夫森结的动力学特性

Dynamics of point Josephson junctions in a microstrip line

J. -G. Caputo, L. Loukitch

摘要:

本文分析了一个新的长波模型,该模型描述了超导腔中点约瑟夫森结阵列的电动力学。它由具有狄拉克δ函数正弦非线性的波动方程组成。我们引入了一个适应的频谱问题,其频谱给出了任何阵列的电流-电压特性曲线中的谐振。利用相关的内积和本征模,我们建立了在共振的解决方案是由两个简单的常微分方程。

英文摘要:

We analyze a new long wave model describing the electrodynamics of an array of point Josephson junctions in a superconducting cavity. It consists in a wave equation with Dirac delta function sine nonlinearities. We introduce an adapted spectral problem whose spectrum gives the resonances in the current-voltage characteristic curve of any array. Using the associated inner product and eigenmodes, we establish that at the resonances the solution is described by two simple ordinary differential equations.
