Japanese and U.S. physicists are offering new details this week in the journal Nature regarding intriguing similarities between the quirky electronic properties of a new iron-based high-temperature superconductor (HTS) and its copper-based cousins.
By measuring how strongly electrons are bound together to form Cooper pairs in an iron-based superconductor, scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, Cornell University, St. Andrews University, and collaborators provide direct evidence supporting theories in which magnetism holds the key to this material's ability to carry current with no resistance.
An international team that includes University of British Columbia physicists has used ultra-fast laser pulses to identify the microscopic interactions that drive high-temperature superconductivity.
As part of an ongoing effort to uncover details of how high-temperature superconductors carry electrical current with no resistance, scientists at Johns Hopkins University and the U.S. Department of Energy's Brookhaven National Laboratory have measured fluctuations in superconductivity across a wide range of temperatures using terahertz spectroscopy.
HZB-Scientists discovered a unique feature of Superconductivity.
New materials yield clues about high-temperature superconductors.
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.
Scientists at the Naval Research Laboratory (NRL) have proposed theoretical models to explain the normal magnetic properties in iron-based superconductors.
