DMRG result of eg under three XC clusters where the circumferences n are 6 (red triangle), 8 (green diamond), and 10 (blue circle). The thick belts are the energy of the zigzag order (green belt) and stripy order (blue belt) obtained by the linear spin-wave theory (LSWT). Inset: Extrapolation of energy for Γ model. For each circumferences n the energy is linearly decreasing with 1/N and the special cases (Lx/Ly = 2) are marked by filled symbols. The extrapolated values fall in the purple band centered at −0.354(3).
