Rare 'Lazarus superconductivity' observed in promising, rediscovered material

A team of researchers has observed a rare phenomenon called re-entrant superconductivity in the material uranium ditelluride. Nicknamed 'Lazarus superconductivity,' the phenomenon occurs when a superconducting state arises, breaks down, then re-emerges in a material due to a change in a specific parameter -- in this case, the application of a very strong magnetic field. The discovery furthers the case for uranium ditelluride as a promising material for use in quantum computers.
