    • note
    • Gaplessness on the square lattice relies on two ingredients in a single-mode calculation: a conservation law, which is present in our case too, for the Hamiltonian only creates and destroys pairs of parallel neighboring dimers and that the conserved quantity, defined in Fig. 2, has an extensive expectation value in a ground state. The conserved quantity is always subextensive on the triangular lattice, at most O(L), and the resonons are gapped.

    • note
    • The corresponding gap in the square lattice staggered phase is O(L), which therefore has no local excitations in the thermodynamic limit.

    • note
    • This is also true at the RK point on the square lattice and is implicit in the results of [6] - note the remarkable feature that raising the temperature confines the spinons. Elsewhere in the square lattice phase diagram, the spinons are confined.
