The discovery of a new class of high-temperature superconductors based on iron tests the limits of current theoretical and computational tools for the understanding of strongly correlated systems.

Compounds called nickelates can conduct electricity without resistance well above absolute zero and at ambient pressure.

"Our study theoretically predicted topological s-wave superconductivity in superconductor materials that include iron-based superconductors," explains Kobayashi. "We revealed a rich topological ...

Exotic superconducting states can exist in common iron-based superconductors, according to a theoretical analysis Figure 1: A diagram showing one case of the energy dispersion of surface states in an ...

The good news is that promising candidates have begun to appear, like iron-based superconductors discovered in 2008. It is becoming increasingly clear that high-temperature superconductivity might ...
