Please help improve it to make it understandable to non-expertswithout removing the technical details. Retrieved from ” https: In contrast to real inductance, no magnetic field is created by a supercurrent in a Josephson junction — the accumulated energy is the Josephson energy.
Note, that although Josephson junction behaves like an inductance, there is no associated magnetic field. By finding the derivative of the current with respect to time, and rearranging in the form of the inductance equation, inductance can be found. A “Dayem bridge” is a thin-film variant of the Josephson junction in which the weak link consists of a superconducting wire with dimensions on the scale of a few micrometres or less.

BIPM[last updated: The work done on the junction so the junction energy is increased by. Josephson was the first to predict the tunneling of superconducting Cooper pairs. The Josephson Inductance is also known as a Kinetic Inductance — the behaviour is derived from the kinetic energy of the charge carriers, not energy in a magnetic field.
The Josephson penetration depth characterizes the typical length on which an externally applied magnetic field penetrates into efecyo long Josephson junction. The Josephson effect is an example of a macroscopic quantum phenomenon. In other projects Wikimedia Commons. This article may be too technical for most readers to understand.

Josephson effect – Wikidata
From Wikipedia, the free encyclopedia. The Josephson effect is the phenomenon of supercurrenta current that flows indefinitely long without any voltage applied, across a device known as a Josephson junction JJwhich consists of two or more superconductors coupled by a weak link [ clarification needed ].
It is named after the British physicist Brian David Josephsonwho predicted in the mathematical relationships for the current and voltage across the weak link. The Josephson effect has found wide usage, for example in the following areas:. Views Read Edit View history.
The weak link can consist of a thin insulating barrier known efeecto a superconductor—insulator—superconductor junctionor S-I-Sa short section of non-superconducting metal S-N-Sor a physical constriction that weakens the superconductivity at the point of contact S-s-S. The basic equations governing the dynamics of the Josephson effect are .
Hence, for efceto AC voltages, the junction may carry a DC current and the junction acts like a perfect frequency-to-voltage converter. This section does not cite any sources. September Learn how and when to remove this template message. This page was last edited on 30 Novemberat
