Extended Data Fig. 6: Tight-binding calculation results for fcc Ti.
From: Observation of the orbital Hall effect in a light metal Ti
a, The electronic band structure of fcc Ti. b, The Fermi surfaces of fcc Ti. Note that there are two Fermi surfaces. The inner and outer surfaces are colored by purple and orange, respectively. c, The orbital texture on the outer Fermi surface. The color implies whether the wave function is more like \({d}_{{z}^{2}-{x}^{2}}\) than \({d}_{{zx}}\) (pink) or vice versa (green) for each crystal momentum k. d, k-resolved orbital Hall conductivity contribution from the outer Fermi surface. It is assumed that an electric field is along the x-direction. The orbital texture and the k-resolved orbital contribution for the inner Fermi surface are given in Figs. 1c and 1d, respectively. e, The orbital (blue) and spin (red) Hall conductivities as a function of the Fermi energy EF. The actual Fermi energy corresponds to EF = 0 eV.
