    • note
    • An alternative quantum generalization would be to follow C. Nayak and K. Shtengel [Phys. Rev. B 64, 064422 (2001)]. In this approach (also pointed out to me by C. L. Henley and S. L. Sondhi), one recognizes that the kinetic energy term is a plaquette operator that flips the currents around a flippable plaquette (as is also the case in the eight-vertex approach). But to this we can add a suitable set of potential energy terms that describe the energetics of the PDW and DDW states. Thus the quantum phase transition in the ground state will be between a DDW state, with many flippable plaquettes, to a PDW state, with no flippable plaquettes. In this alternative approach, the quantum phase transition would be very similar to the quantum dimer model exhibiting a transition between an ordered state with many flippable plaquettes to the ordered valence bond crystal state with no flippable plaquettes (Ref. 9). This is also a possible, but I feel unlikely, alternative in the eight-vertex approach taken in the main part of the text. Some care is necessary for setting up the parallel with the quantum dimer model, however: (a) the number of states in the dimer model is 4 not 6. (b) The time reversal symmetry is broken in the DDW state, but not in the dimer model. As of of this moment, I have been unable to construct a precise Hamiltonian in this manner, which reduces exactly to the six-vertex model in the classical limit, but I have no doubts that it could be done.
