Abstract
The recently discvoered topological spin-triplet superconductor UTe${}_{2}$ is thought to have anisotropic electronic band structure, yet measurements of normal-state electrical transport anisotropy have remained elusive. In this study, the authors develop and employ a generalized Montgomery resistance measurement technique to fully characterize the absolute transport anisotropy of UTe${}_{2}$, finding that the $c$-axis resistivity is surprisingly not quantitatively anisotropic, but rather qualitatively different from $a\ensuremath{-}b$ plane resistivities.
