Nodal Superconductivity of UTe${}_2$ Probed by Field-Angle-Resolved Specific Heat on a Crystal with $T_{\mathrm{c}}=2.1$ K

Kaito Totsuka, Yohei Kono, Yusei Shimizu +6

Field-angle-resolved specific-heat measurements were performed on a clean single crystal of a spin-triplet superconductor UTe${}_2$ with $T_{\mathrm{c}}=2.1$ K and a low residual electron…
