He observed that when mercury was cooled to below minus-452 degrees Fahrenheit, about 7 degrees above absolute zero, electrical resistance suddenly disappeared, and mercury was a superconductor. For physicists, that was astounding, almost like happening upon a real-world perpetual motion machine. Indeed, an electrical current running around a ring of mercury at 7 degrees above absolute zero would, in principle, run forever. If the phenomenon defied intuition, it also defied explanation.

B (issue of April 2004) Title and Authors 1 May 2004 Ghost of Superconductivity on a Fall Day Alan Hewat / Institut Laue-Langevin Super structure. When some of the lanthanum atoms (blue) in La CuO are replaced with strontium atoms, the material conducts electricity without resistance up to about 40 kelvin. But even at 290 kelvin, near room temperature, the material shows some possible hints of the superconducting state. Materials that conduct electricity without resistance continue to surprise physicists. In the April Physical Review B , one of the so-called high-temperature superconducting (HTS) materials shows a magnetic effect typical of superconductivity even at the temperature of a cool autumn dayfar above its temperature for resistance-free current. The results reinforce other experiments suggesting that a "shadow" of the superconducting state exists even when the material appears normal and may give clues about the underlying causes of the HTS phenomenon. Superconductivity occurs if electrons form pairs when a material is cooled. These pairs can join to form a collective quantum mechanical state that extends throughout a chunk of material and carries electric current with no resistance. In "traditional" superconductors like aluminum, this state forms at the same ultra low temperature as the electron pairs do. By contrast, the HTS materials show indications of pairs even near room temperature but become superconducting only at much lower temperatures (though still warm compared with traditional superconductors). One model proposes that pairing occurs only in narrow "stripes," while resistance-free electric current is blocked by intervening stripes of magnetism [

States of Matter Solid State Physics Superconductivity Superconductivity A phenomenon in which a substance loses all electrical resistance first discovered in metals at liquid helium temperatures by Kamerlingh-Onnes in 1911. The BCS theory does not appear capable of explaining the high-temperature phenomenon, although extending the phonon propagation with an s -wave may work. However, the most recent experiments seem to favor a new d -wave mechanism in which electrons are propagated by magnetic fluctuations (Clery 1996). Meissner Effect Anderson, P. W.

Hole Superconductivity The theory of hole superconductivity (also known in some circles as 'The holistic theory of superconductivity') asserts that superconductivity can only occur when 'hole' carriers exist in the normal state of a metal. A 'hole' is the absence of an electron, and hole carriers exist when an electronic energy band is almost full. Holes are different from electrons , as the picture to the right clearly shows. A hole in a full band has difficulty propagating due to the disruption it causes in its environment. Superconductivity occurs due to pairing of hole carriers, and is driven by the fact that paired holes can propagate more easily (have a smaller effective mass) than single holes. As a consequence, their kinetic energy is lowered. In contrast, single electrons can move easily and so they don't pair. ' Dynamic Hubbard models ' describe the different physics of electron and hole carriers in metals. The different mobility of holes and electrons can be illustrated by a garage analogy.

Superconductivity Superconductivity is infinitely more than a physics phenomena of the first order. It may be one of the fundamental linking mechanisms in an unlimited and connected universe. The physics is referenced, for example, in the Scientific References , but for those looking for a quick and dirty explanation, the following will provide an inkling of the immensity of the subject. Just keep in mind that any U. S. patent application which includes anywhere in its text the word “superconductivity” is automatically sent to the Department of Defense for review. That should be convincing evidence that this subject is worth investigating. Most, but not all, conductors of electrical current, when cooled sufficiently in the direction of absolute zero (0 o K, -273.15 o C), become superconductors. The superconducting state itself is one in which there is zero electrical resistance and perfect diamagnetism. [1] This means that current flowing through a superconducting circuit does not experience i R heating (current squared times the resistance), and the current can flow indefinitely. Also, diamagnetism is the property of a substance to become magnetized in a direction at right angles to an applied magnetic field (Michael Faraday discovered the effect in 1846 that when such substances were brought near the pole of a strong magnet, they were

FYI: Science Policy News Bulletin Number 752 November 2, 2005 by Phil Schewe and Ben Stein Color Superconductivity Color superconductivity, the hypothetical condensation of quark pairs at the cores of super-dense collapsed stars, might represent a unique example of superconductivity being made stronger, not weaker, by the presence of magnetism. In ordinary electrical superconductivity, in a metallic lattice of atoms, free electrons can pair up through the agency of a very weak coupling force mediated by the subtle vibrations in the lattice itself, establishing a weakly attractive force between pairs of electrons. An external magnetic field is either repelled from such a superconducting environment (the Meissner effect) or can serve to undo the fragile superconducting state. On the other hand, if quark matter is realized inside the core of neutron stars with densities about 10 times the density of ordinary atomic nuclei or within the still hypothetical quark stars objects ranking somewhere between neutron stars and black holes in terms of matter density quarks will be pressed together so firmly that by the rules of asymptotic freedom (see the description of last year's physics Nobel prize in PNU 703 ) the force between the quarks will be quite weak and attractive.
