Chiral crystals with spin-orbit coupling (SOC) termed Kramers Weyl semimetals possess Weyl points at time-reversal invariant momenta. Here, the authors propose a new class of topological materials with doubly degenerate lines connecting time-reversal invariant momenta in achiral noncentrosymmetric materials with SOC.
