Latest High-temperature superconductivity Stories
Brown University physicist Vesna Mitrovic and colleagues at Brown and in France have discovered magnetic waves that fluctuate when exposed to certain conditions in a superconducting material.
Research Superiority Award to Enable Recruitment of Stellar Faculty, Formally Establish Applied Research Hub at Texas Center for Superconductivity (TcSUH-ARH) HOUSTON, Feb.
Neutron scattering experiments performed at the Department of Energy's Oak Ridge National Laboratory give strong evidence that, if superconductivity is related to a material's magnetic properties, the same mechanisms are behind both copper-based high-temperature superconductors and the newly discovered iron-based superconductors.
Physicists have long wondered whether hydrogen, the most abundant element in the universe, could be transformed into a metal and possibly even a superconductorâ€”the elusive state in which electrons can flow without resistance.
First direct evidence of quantum critical point in iron-based 'pnictides'.
Findings may lead to precision engineering of superconducting thin films for electronic devices.
In finally answering an elusive scientific question, researchers with the U.S. Department of Energyâ€™s Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that the selective placement of strain can alter the electronic phase and its spatial arrangement in correlated electron materials.
Canadian scientists are challenging physics' single-band Hubbard theory that's used to predict and calculate behavior of high-temperature superconductors. University of British Columbia researchers said their findings mark the first compelling evidence challenging the Hubbard model under certain conditions, and could necessitate entirely new theoretical approaches to explaining superconductivity in certain materials. Single-band Hubbard physics has been used for 20 years to predict how...
New UBC research has literally and figuratively poked holes in single-band Hubbard physics--a model that has been used to predict and calculate the behavior of high-temperature superconductors for 20 years.
Superconductivity appears to rely on very different mechanisms in two varieties of iron-based superconductors.
