Proliferation of topological defects like vortices and dislocations plays a key role in the physics of systems with long-range order, particularly, superconductivity and superfluidity in thin films, ...

Bose condensation happens in a gas of atoms when the de Broglie wavelength of the atoms becomes comparable with their average separation. All the atoms in the gas then collapse into the same quantum ...

The Josephson junction is one of the most important elements in turning quantum phenomena into usable technology. A new RMIT study establishes a theoretical framework for new optical experimentation ...

Arrays containing as many as 20,000 Josephson junctions have been created by physicists at CSIRO in Australia. The devices are made from a high-temperature superconductor and operate at ...

The Josephson effect is the phenomenon of supercurrent, a current that flows continuously without any voltage applied, across a device known as a Josephson junction (JJ), which consists of two or more ...

Since the prediction 1,2,3 and subsequent observation 4,5 of single charge tunnelling in small metallic tunnel junctions, the field of low temperature nanoelectronics has developed rapidly.

Researchers have devised a novel, inexpensive way to turn low frequency signals into higher frequencies. The approach makes use of a Nobel Prize-winning device called a Josephson junction, which is ...
