Fig. 4: DFT and ARPES along and perpendicular to the KNL.
a The band structure of LaTe3 in the CDW state with the 7f structure along \(X{{\Gamma }}{Z}^{{\prime} }Z\). On the left, zoomed regions from the blue rectangles show the two fold degeneracy (dashed-green and black) of the bands along the KNL. On the right, zoomed regions from the red rectangles show the spin-splitting along the ΓZ direction in contrast to ΓX. The bands that cross EF are highlighted by orange and green shading. b ARPES intensity plot measured using photon energy of 24.4 eV, and c the EBS obtained from DFT towards ΓX and ΓZ. The white dashed curves in b serve as guide to the eye for some of the bands that are numbered from 1 to 19. The orange double sided arrows indicate the CDW gap. All the panels share the same x axis.
