Uranium ditelluride is an inorganic compound with the formula UTe2. It was discovered to be an unconventional superconductor in 2018.[1]

Superconductivity

Superconductivity in UTe2 appears to be a consequence of triplet electrons spin-pairing.[2] The material acts as a topological superconductor, stably conducting electricity without resistance even in high magnetic fields.[1] It has superconducting transition temperature at Tc= 2K.[3]

Charge density waves (CDW)[4] and pair density waves (PDW)[5][6][7] have been described in UTe2, with the latest case being the first time it has been described in a p-wave superconductor.
