Orbital angular momentum of the surface states. a The fourfold crossing of the SS and SS\(^{\prime}\) surface states in our tight-binding model (see Methods section). A magnified view of crossing #3 is shown inset. b Reproduction of the tight-binding dispersions from a, with the calculated expectation value of the orbital angular momentum along the \(x\) quantisation axis shown as symbol colour/size. c Schematic of the fourfold crossing of SS and SS\(^{\prime}\) surface states. The crossings are numbered as in Fig. 2c, and ket labels on the bands represent the orbital and spin angular momenta of the bands in our minimal model.
