From: Bulk RKKY signatures of topological phase transition in silicene
The phase diagrams of (a) J z , (b) \({J}_{\parallel }\), and (d) J DM as functions of U and Ω. (c) The comparison between the phase boundary (black dashed lines) and the dip position of J z (red circles) which is selected from the local minimum value in (a). Different phases are labeled by different quantum numbers (C, C s ), which represent for charge- and spin-Chern numbers, respectively. The chosen parameters are E F  = 0 and R = 271a.
