Oak Ridge National Laboratory Nearly 30 years after the discovery of high-temperature superconductivity, many questions remain, but an Oak Ridge National Laboratory team is providing insight that could lead to better superconductors. Their work, published in Physical Review Letters, examines the role of chemical dopants, which are essential to creating high-temperature superconductors – materials that conduct electricity without resistance. The role of dopants in superconductors is...

Universal Ripple May Hold Secret To High-temperature Superconductivity
2013-12-20 15:08:38

University of British Columbia UBC researchers have discovered a universal electronic state that controls the behavior of high-temperature superconducting copper-oxide ceramics. The work, published this week in the journal Science, reveals the universal existence of so-called 'charge-density-waves' -- static ripples formed by the self-organization of electrons in the material's normal state. These ripples carry the seeds out of which superconductivity emerges. "Our understanding of...

Grand Unified Theory Of Exotic Superconductivity?

Brookhaven National Laboratory Scientists introduce a general theoretical approach that describes all known forms of high-temperature superconductivity and their "intertwined" phases Years of experiments on various types of high-temperature (high-Tc) superconductors—materials that offer hope for energy-saving applications such as zero-loss electrical power lines—have turned up an amazing array of complex behaviors among the electrons that in some instances pair up to carry current...

2 orders for electrons A German-French research team has constructed a new model that explains how the so-called pseudogap state forms in high-temperature superconductors. The calculations predict two coexisting electron orders. Below a certain temperature, superconductors lose their electrical resistance and can conduct electricity without loss. "It is not to be excluded that the new pseudogap theory also provides the long-awaited explanation for why, in contrast to conventional metallic...

A multi-university team of researchers has artificially engineered a unique multilayer material that could lead to breakthroughs in both superconductivity research and in real-world applications. The researchers can tailor the material, which seamlessly alternates between metal and oxide layers, to achieve extraordinary superconducting properties – in particular, the ability to transport much more electrical current than non-engineered materials. The team includes experts from the...

New Superconducting Materials Improve the Efficiency and Reliability of Grids and Systems For the first time, a superconducting current limiter based on YBCO strip conductors has now been installed at a power plant. At the Boxberg power plant of Vattenfall, the current limiter protects the grid for own consumption that is designed for 12 000 volts and 800 amperes against damage due to short circuits and voltage peaks. The new technology co-developed by Karlsruhe Institute of Technology and...

Researchers from North Carolina State University have developed a new computational approach to improve the utility of superconductive materials for specific design applications — and have used the approach to solve a key research obstacle for the next-generation superconductor material yttrium barium copper oxide (YBCO). A superconductor is a material that can carry electricity without any loss — none of the energy is dissipated as heat, for example. Superconductive materials...

Discovery in parent of one high-temperature superconductor may lead to predictive control A team of scientists studying the parent compound of a cuprate (copper-oxide) superconductor has discovered a link between two different states, or phases, of that matter - and written a mathematical theory to describe the relationship. This work, appearing in the July 22, 2011, issue of Science, will help scientists predict the material's behavior under varying conditions, and may help explain how it's...
