Superconducting Triple Point in UTe2: Thermodynamics and Symmetry
Abstract
Three lines of second-order phase transitions between the normal phase and two distinct superconducting phases meet at a single point on the phase diagram of UTe2. Although it is commonly believed otherwise, such triple points are not subject to thermodynamic constraints. The phase diagram is interpreted within Landau theory in terms of two superconducting order parameters with different gauge symmetries. Such an interpretation is unique under the assumption of spatial uniformity.
