Superconductors with ‘zeitgeist’ – when materials differentiate between the past and the future

What happened yesterday and what will happen tomorrow are usually two different and quite independent matters. The past and the future of human life are not…

Electronic map reveals 'rules of the road' in superconductor

Using a clever technique that causes unruly crystals of iron selenide to snap into alignment, Rice University physicists have drawn a detailed map that reveals…

Ames Laboratory scientists gain insight on mechanism of unconventional superconductivity

Researchers combined innovative crystal growth, highly sensitive magnetic measurements, and the controlled introduction of disorder through electron…

The cause of high Tc superconductivity at the interface between FeSe and SrTiO3

Raising the superconducting transition temperature, the temperature above which a superconductor turns into a normal conductor, to a point where applications…

Optimizing electronic correlations for superconductivity

Samples from two classes of iron-based superconductors, pnictides and chalcogenides, employ similar coupling between electrons in their superconducting state,…
