(Phys.org) —To engineers, it's a tale as old as time: Electrical current is carried through materials by flowing electrons. But physicists at the University of Illinois and the University of ...

A cuprate material was briefly exposed to high pressure so that it remains superconducting at a higher temperature.

The discovery of superconductivity in cuprates, a class of ceramic materials, in 1986 has boosted an impressive effort of research all around the world. These materials still hold the record for the ...

The finding could help future efforts to design superconductors that work at higher temperatures. For the past century since their discovery, superconductors and their mysterious atomic properties ...

In their quest to explore and characterize high-temperature superconductors, physicists have mostly focused on a material that is not the absolute highest. That's because that crystal is much easier ...

Despite being vital to the study of superconductivity in cuprate materials the physical origins of the pseudogap remain a mystery. Over three decades since the discovery of high-temperature ...

Universal scaling laws can guide the understanding of new phenomena, and for cuprate high-temperature superconductivity the influential Uemura relation showed, early on, that the maximum critical ...
