From Quantum Dimers to the $\pi$-flux Toric Code via Deconfined Multicriticality

Ankush Chaubey, Sergej Moroz, Subhro Bhattacharjee

Two-dimensional Rokhsar-Kivelson (RK) dimer models on bipartite lattices are generally limited to translation-symmetry-broken dimer crystals. We introduce a tensor-product regulari…
