Bulk band inversions in solids may unlock topological surface phenomena and symmetry-protected states. Here, the authors generate a surface state band inversion in the nonsymmorphic semimetal NbGeSb, leading to protected crossing points in the resulting spin-orbital entangled surface band structure.
