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.
