Boost and Suppression of High Field Superconducting Phases in UTe2 under Pressure

The heavy fermion superconductor UTe$_{2}$ hosts an unusual superconducting phase that exhibits hallmarks of spin-triplet pairing, multiple order parameters, time-reversal symmetry breaking, and in-gap surface states. Some of the most exceptional features are evident in high magnetic field, namely, a critical field of 35 T that coincides with a metamagnetic transition, and a large pocket of reentrant superconductivity at even higher fields at field angles in between the crystallographic b- and c-axes. In this talk, I will discuss the evolution under pressure of multiple superconducting and other phases, with a focus on high magnetic fields.
