Josephson effect

The Josephson-effect device has been credited with revolutionising the measurement of high voltages. In 1989, Lloyd shared the US Commerce Department's Gold Medal for contributions to voltage standards. Frances Lytle Lummis was born in Honolulu in the early 1920s. She accompanied her father on ...

This fundamental quantum circuit element is the dual and opposite to the Josephson junction – based on the Noble Prize winning Josephson effect – and underlines the CQUID's potential. The CQPS junction is realised in the circuit by embedding a superconducting nanowire in a very high-impedance ...

Optical control of states exhibiting macroscopic phase coherence in condensed matter systems opens intriguing possibilities for materials and device engineering, including optically controlled qubits and photoinduced superconductivity. Metastable states, which in bulk materials are often associated with ...

The Josephson effect is a macroscopic quantum phenomenon that reveals the broken symmetry associated with any superfluid state. Here we report on the observation of the Josephson effect between two fermionic superfluids coupled through a thin tunneling barrier. We show that the relative population and phase are ...

It was pointed out by Fu and Kane [4], following a proposal in a different context by Sato [5], that the interface between a conventional superconductor and a topological insulator supports such Majorana levels in magnetic vortices, and that Majorana levels can lead to a modification of the Josephson effect.

A fundamental prediction of superconductivity theory has been demonstrated in the lab for the first time. An international team of physicists has observed coherent quantum phase slip, a phenomenon similar to the well-known Josephson effect in which magnetic flux takes the place of electric charge.

1) is similar to the flow of a supercurrent across a barrier between two superconducting regions (Josephson effect). In their system of double-bilayer graphene, Tutuc and colleagues observed one of these experimental signatures—Josephson-like tunneling [3]. The device was built from two sheets of bilayer ...
