Fig. 14: Dual lattice and dimer model.
From: Wannier states and spin supersolid physics in the triangular antiferromagnet K2Co(SeO3)2
a Triangular lattice (gray line) and the associated honeycomb dual lattice (bold line). The green bonds denote the “special” ones used in the unitary transformation. The blue dashed lines show a resonant hexagon and the red boxes represent the dimer covering. b Effect of the effective Hamiltonian over a resonant hexagon, the same that in (a), the number of special bonds covered by dimers is represented by Ns.
