Kramers Nodal Lines (KNLs) have been theoretically proposed as special Weyl line degeneracies connecting time-reversal invariant momenta, but their observation in quantum materials is not established. Combining ARPES experiments with DFT calculations, the authors identify SmAlSi and its isostructural family as viable materials to host KNLs.
