Fig. 1: The KΓ ladder and corresponding phase diagram.

a A strip of the KΓ honeycomb lattice corresponding to a two-leg KΓ ladder with alternating x and y bonds along the leg and z-bond between the chains, with the numbering of the sites used throughout the paper. The dotted z-bonds arise from imposing periodic boundary conditions in the direction perpendicular to the ladder. However, all z-bonds are taken to have equal strength. The dashed red line indicates the partition used for ρB while the dashed blue line indicates the partition used for ρA. b Schematic phase diagram of the KΓ ladder, Eq. (1), for Γ > 0.
