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] With recent crystal growth techniques a superconducting transition temperature of 2.10 K has been reached as of 2025. [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.
