Extreme spin-triplet superconductivity in uranium ditelluride - CANCELED

We recently discovered a new superconducting state in UTe2 below 1.6 K. This state emerges from a heavy fermion normal state, coexists with strong spin fluctuations, has an extremely high upper critical field of 35 T, and supports an even higher-field reentrant superconducting phase between 40 T and 65 T.  In this talk, I will describe how superconductivity in UTe2 dramatically differs from conventional superconductivity, and I will argue that it is topologically nontrivial.
