Onnes coined the term superconductivity and showed that tin and lead, too, become superconducting at very low temperatures.
The demand that I see making the difference most from a usage point of view (barring some new breakthrough in superconductivity), concerns the anti-microbial uses of the product.
However, like in superconductivity (see below) pairs of spin-half particles can form "quasi-bosons" that can condense into a superfluid phase.
In all the years with IBM Research, I have especially appreciated the freedom to pursue the activities I found interesting, and greatly enjoyed the stimulus, collegial cooperation, frankness, and intellectual generosity of two scientific communities, namely, in superconductivity and critical phenomena.
Room-temperature superconductivity is "definitely at the back of people’s minds," notes David Snoke, a University of Pittsburgh physicist who also does research on novel Bose-Einstein condensates.
In the 1960's, another development in superconductivity was initiated, by the Englishman Brian Josephson (who received the
The understanding of high temperature superconductivity, which is still not complete, has gained from concepts developed for helium-3, giving examples of the interactions that lead to pairing of particles in strongly interacting systems as well as for the symmetry of the wave function for such pairs.
The term superconductivity refers to the complete disappearance of the electrical resistance, which was later verified with an enormous accuracy.
The term superconductivity refers to the complete disappearance of the electrical resistance.
The landmark finding by Riken Institute researchers involves the classical theory that superconductivity occurs when two electrons are bound together to form a pair, known as a Cooper pair, by lattice vibrations.
