Terahertz light from superconducting stripes

Scientists discover anomalous emission of terahertz radiation from copper oxides in which superconductivity coexists with charge-stripe order

27-Sep-2022

Why do some materials carry electrical currents without any resistance only when cooled to near absolute zero while others do so at comparatively high temperatures? This key question continues to vex scientists studying the phenomenon of superconductivity. Now a team of researchers from Andrea ...

Titanium hosts record high superconductivity for elements superconductors

Titanium breaks record of Tc for element superconductors

21-Sep-2022

Element superconductors are important either for superconducting mechanism studies or for potential applications because of the single composition. However element superconductor (SC) usually show very low transition temperature (Tc) typically below 10K. Recently Prof. Changqing Jin’s team at ...

Low pressure, high stakes: UNLV physicists make major gains in race for room-temperature superconductivity

Newly published research builds on team’s landmark 2020 discovery of a room-temperature superconductor by replicating results with even greater efficiency

08-Aug-2022

Less than two years after shocking the science world with the discovery of a material capable of room-temperature superconductivity, a team of UNLV physicists has upped the ante once again by reproducing the feat at the lowest pressure ever recorded. In other words, science is closer than ...

Study finds nickelate superconductors are intrinsically magnetic

Waves of magnetic excitation sweep through this exciting new material whether it’s in superconducting mode or not

03-Aug-2022

Electrons find each other repulsive. Nothing personal – it’s just that their negative charges repel each other. So getting them to pair up and travel together, like they do in superconducting materials, requires a little nudge. In old-school superconductors, which were discovered in 1911 and ...

A new leap in understanding nickel oxide superconductors

27-Jul-2022

A new study shows that nickel oxide superconductors, which conduct electricity with no loss athigher temperatures than conventional superconductors do, contain a type of quantum matter called charge density waves, or CDWs, that can accompany superconductivity. The presence of CDWs shows that ...

Superconductivity: New tricks for finding better materials

Nickelates are a new promising material for future superconductivity technologies: Scientists have now succeeded in explaining their electronic structure.

26-Oct-2021

Even after more than 30 years of research, high-temperature superconductivity is still one of the great unsolved mysteries of materials physics. The exact mechanism that causes certain materials to still conduct electric current without any resistance even at relatively high temperatures is still ...
