Uranium ditelluride
Uranium ditelluride is an inorganic compound with the formula UTe2. It was discovered to be an unconventional superconductor in 2018.
Superconductivity
Superconductivity in UTe2 appears to be a consequence of triplet electrons spin-pairing. The material acts as a topological superconductor, stably conducting electricity without resistance even in high magnetic fields. With recent crystal growth techniques a superconducting transition temperature of 2.10 K has been reached as of 2025.Charge density waves and pair density waves have been described in UTe2, with the latest case being the first time it has been described in a p-wave superconductor.
