Abstract
The characteristic behavior of the inductance and capacitance of multi junction ac Josephson effect in superconductor has been presented. Few parameters characterizing the behavior of Josephson junctions are needed to evaluate for technological applications. In this paper, the inductance and capacitance of the multi Josephson junction connected in parallel are evaluated, using simple classical argument. The numerical results for inductance and capacitance have also been included, indicating few technological applications.
Highlights
The Josephson effect [1] [2] is a macroscopic quantum phenomenon in superconductivity
We have studied the model of multi Josephson junction in superconductivity
The theoretical investigation based on numerical analysis of the characteristic parameters of multi Josephson junction indicates few technological advantages, like high frequency oscillator, interferometer, and qubit etc. already mentioned before
Summary
The Josephson effect [1] [2] is a macroscopic quantum phenomenon in superconductivity. The coherence nature of Cooper pair in superconductor gives macroscopic quantum interference effect analogous to optical physics. The tunneling Cooper pair causes spontaneous supercurrent through the Josephson junction without applied voltage called dc Josephson effect and the supercurrent is proportional to the sine of the difference of phases of two superconductors. This is a very strange phenomenon in physics. The Josephson junction is considered as an electronic analogue and behaves like an inductor and capacitor This behavior is not true only for single Josephson junction and for multi junctions.
