Latest High-temperature superconductivity Stories
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.
Superconductivity is a unique state in which electrons move freely inside a solid material. This complete lack of electrical resistance could translate to incredibly efficient electric power cables, as well as many other promising technologies.
Researchers at the National Institute of Standards and Technology (NIST) have discovered that a reduction in mechanical strain at the boundaries of crystal grains can significantly improve the performance of high-temperature superconductors (HTS).
Multiferroics are materials in which unique combinations of electric and magnetic properties can simultaneously coexist.
