Angular dependence of the quantum oscillation frequencies of SmB6 from Ref. [15] (a) and Ref. [16] (b). In the case of the former, the angular dependence was reported as being consistent with a 2D Fermi surface, as expected if the quantum oscillations arise from a surface state. On the other hand, the angular dependence of the frequencies in panel (b) was reported to be much more consistent with three-dimensional Fermi surfaces, pointing to a bulk origin.
