a, b Numerically calculated LDOS maps around a single magnetic impurity for the hole-like YSR bound state considering a a circular and b a hexagonal Fermi surface (FS). c Direct comparison between the calculated LDOS with the realistic FS of La(0001) (left) and the experimentally obtained dI/dV map at E = −EYSR (right). Scale bar: 10 atomic sites (simulations), 4.0 nm (experiment). For details of the model and the calculation parameters, see Methods, Supplementary Notes 5 and 6, Supplementary Figs. 5 and 6. The corresponding shapes of the FS are depicted in the inset for each calculated image. The intensity scale of all calculated LDOS maps is the same, to be able to compare them directly with each other.
