Exploring the full phase diagram of UTe2 below the metamagnetic transition

ORAL

Abstract

In this talk, I will present the phase diagram of UTe2 below Tc with magnetic fields up to 40 T applied in various directions. I will show how this full phase diagram adds evidence for a distinction between the zero-field superconducting phase of UTe2 and the superconducting phase that emerges with field applied along the b axis. Additionally, I will discuss how the data we’ve gathered deviates from a simple anisotropic effective mass model of superconductivity and what may underlie this deviation.
