For the first time, physicists have experimentally validated a 1959 conjecture that places limits on how small superconductors can be. Understanding superconductivity (or the lack thereof) on the nanoscale is expected to ...
(Phys.org)—Scientists have found that a superconducting current flows in only one direction through a chiral nanotube, marking the first observation of the effects of chirality on superconductivity. Until now, superconductivity ...
(Phys.org)—Due to their electronic and magnetic properties and their association with crystalline and electronic structures under extreme conditions, three-dimensional (3D) Dirac semimetals – that is, materials that possess ...
(Phys.org)—Physicists have proposed that a hypothetical form of matter called "unparticles" may play a key role in mediating superconductivity—the ability of certain materials to conduct electricity with zero resistance.
(Phys.org)—Superconductivity – perhaps the leading example of emergent quantum behavior in matter – was discovered in 1911 but lacked theoretical explanation for almost five decades. In 1957, John Bardeen, Leon Cooper, ...
(Phys.org) —Cooling microscopic objects to temperatures near absolute zero requires unconventional refrigeration technologies. One microscale cooling method is superconducting refrigeration, in which refrigerators extract ...
(Phys.org) -- Superconductivity is a complex phenomenon that is considerably more intricate than many casual observers realize. This caveat applies equally to the subset of this research known as high-temperature superconductivity ...
(PhysOrg.com) -- The quest to develop a so-called room-temperature superconductor – one that exhibits lossless electronic transmission – has long fueled both popular and scientific imagination. At the same time, ...
(PhysOrg.com) -- "Chiral superconductivity is the dream of mankind," Carlo Beenakker tells PhysOrg.com. "All sorts of scientists are working on it, and there are many labs trying to create materials that are predicted to ...
(PhysOrg.com) -- Recently, an international group of researchers discovered that the underlying mechanism producing high-temperature superconductivity in a widely studied class of copper-oxygen-based superconductors may be ...
