From: Reentrant topological phases and spin density wave induced by 1D moiré potentials
a and c The real-space spin density fluctuation δSj plotted for non-interacting case with U = V = 0 (a), and interacting case with U = V = 1 (c). Solid lines for mo = 0 and dashed curves for mo = 0.01. Inset plots are the charge density fluctuation δnj for mo = 0.01 where no CDW occurs. (b and d) The momentum-space spin density fluctuation δSk for the non-interacting and interacting cases in (a and c), respectively. e The maximum local spin density \({{S}_{k}}^{\max }\) as functions of mo for non-interacting (black circles) and interacting (blue squares) cases. f The scaling of maximum local spin density versus system size L = 21A with A = 2, 4, 8, 16 for the non-interacting (solid lines) and interacting (dashed lines) cases. Other parameters are ts = 0.95 and mz = 2.4.
