We note that the two-dimensional quantum (Formula presented) model with bond disorder has been suggested to have a spin-liquid ground state for a large enough concentration of frustrating bonds: see P. Gawiec and D.R. Grempel, Phys. Rev. B 54, 3343 (1996).

Only part of the degeneracy is actually removed: the spin-liquid ground state turns out to have an extensive entropy in the large-(Formula presented) limit, as studied in detail in Ref. 34

Note that, strictly speaking, there is no Fourier transform on the Bethe lattice. (Formula presented) dependence should really be interpreted as a dependence on the single-particle tight-binding energy (Formula presented)
