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.

A team of engineers and physicists at Southern University of Science and Technology, in China, has created a nickel-based material that behaves as a superconductor above the -233°C (40 K) threshold ...

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 ...
