Wang and a team of researchers demonstrated such light can be used to control some of the essential quantum properties of superconducting states, including macroscopic supercurrent flowing, broken symmetry and accessing certain very high frequency quantum oscillations thought to be forbidden by symmetry.
The supercurrent operator emerging from this approach coincides with (7) (see eq.
When an external magnetic field is applied to the superconducting loop, a supercurrent flows to maintain a zero flux through the loop.
His theory predicted the properties of a supercurrent through tunnel barriers known as the Josephson effect.
Some known intermittent external noise sources were RF interference (e.g., a nearby shortwave transmitter), mechanical vibrations (lawn mowers, local construction), or a coincidence with magnet supercurrent fluctuations (recorded separately).
Josephson's theoretical predictions of the properties of supercurrent through a tunnel barrier earned him the Nobel Prize in 1973.
Because of the unique properties of the supercurrent in the Josephson junction,|9,10~ the SQUID has a nonlinear inductance that can be described by
At about the same time supercurrent junctions were found to exhibit the Josephson effect, namely, the flow of an electron-pair tunneling current through an insultor separating two superconductors.
GL equations were solved using natural boundary conditions, i.e., supercurrent across the boundaries is zero and magnetic field at the boundaries is given as follows:
The need to characterize the misorientation of hundreds of grain boundaries in polycrystalline superconductors to understand the barriers to supercurrent flow led him to develop strong skills in electron backscatter Kikuchi diffraction, which was a fledgling field in the early 1990s.
Along with four other scientists, the Cardiff physicist won the Nobel Prize for physics in 1973 for his theory on predicting the properties of a supercurrent through tunnel barriers - known as the "Josephson effect".
