$\mathrm{U}{\mathrm{Te}}_{2}$ is a likely spin-triplet superconductor that also exhibits evidence for chiral Majorana edge states. A characteristic structural feature of $\mathrm{U}{\mathrm{Te}}_{2}$ is inversion-symmetry related pairs of U atoms, forming rungs of ladders. Here we show how each rung's two sublattice degrees of freedom play a key role in understanding the …
