Andrey Geim of the Universities of Nijmegen and Manchester, and co-workers from Russia, Belgium and the UK, measured the amount of flux entering micron-sized aluminium discs, where edge effects are im...
Hendrik Schon, Christian Kloc and Batlogg investigated three different acenes: anthracene (which contains three linked rings), tetracene (four) and pentacene (five). The crystals are normally insulati...
The device has three electrodes: a niobium injector electrode; a common electrode that consists of a layer of niobium and a layer of aluminium; and a niobium detector electrode. The electrodes are sep...
In his original thought experiment, Schrodinger imagined that a cat is locked in a box, along with a radioactive atom that is connected to a vial containing a deadly poison. If the atom decays, it cau...
Most materials only become superconducting when they are cooled to low temperatures. In this state the electrons inside the material overcome their natural repulsion and travel through the material in...
The neutron scattering experiments were carried out by Herb Mook from the Oak Ridge National Laboratory and colleagues, while the ion channelling experiments were performed by Rajeshwar Sharma from th...
While theorists have been battling to understand high-temperature superconductivity, industry is developing devices ready for a global marketplace potentially worth billions of dollars
The origin of high-temperature superconductivity in cuprate materials is one of the biggest puzzles in physics, explain Bertram Batlogg and Chandra Varma
Even a decade and a half after the discovery of high-temperature superconductivity in ceramic compounds containing copper-oxide planes, these materials continue to puzzle condensed-matter theorists. T...
There is an old joke about a farmer who has a hen that will not lay eggs. After consulting unsuccessfully with a biologist, and then a chemist, he finally turns to a theoretical physicist. Several day...
