The newly discovered superconductor $\mathrm{U}{\mathrm{Te}}_{2}$ is a strong contender for a topological spin-triplet state wherein a multicomponent order parameter arises from two nearly degenerate superconducting states. A key issue is whether both of these states intrinsically exist at ambient pressure. Through thermal expansion and calorimetry, we show that $\mathrm{U}{\mathrm{Te}}_{2}$ at …
