Fig. 2: Spin and orbital textures of electronic states.

Constant energy lines with spin and orbital textures at selected energies. Panels a–d Iso-energy lines slightly above the band edges of the four band pairs. The upper quadrants display the spin texture (red arrows), the lower quadrants the orbital expectation values (blue arrows). Left quadrants correspond to the outer band of a pair, right quadrants to the inner band. The contours for which the spin or orbital textures are shown are drawn as slightly thicker lines. e detail of panel c. Here, all quadrants show the textures of both bands. f detail of panel d, only the second band pair (green) is shown.
