    • These topological excitations certainly do not exhaust the degrees of freedom. In particular, there will be neutral, transverse phononlike excitations of the RVB degrees of freedom.

    • The true RVB ground state will certainly contain an admixture of virtual soliton-antisoliton pairs. However, topological long-range order, similar to that in the XY model, may survive.

    • We are assuming that the dispersion relation is not completely changed by the exotic order of the RVB state. Also, our analysis is substantially unchanged in discussing three-dimensional cubic systems, except that the mass of the solitons will be larger. The binding energy of the charged soliton is not strongly dependent on dimension; thus the possibility exists that bosons could exist above their condensation temperature in three dimensions.

    • Both interlayer couplings and attractive interactions between charged solitons (mediated, for example, by exchange of neutral solitons) should allow Bose condensation, which, strictly speaking, will not occur in a noninteracting two-dimensional system.
