We study a generalized quantum hard-core dimer model on the square andhoneycomb lattices, allowing for first and second neighbor dimers. Atgeneralized RK points, the exact ground states can be constructed, andground-state correlation functions can be equated to those of interacting 1+1dimensional Grassmann fields. When the concentration of second neighbor dimersis small, the ground state correlations are shown to be short-rangedcorresponding to a (gaped) spin liquid phase. On a 2-torus, the ground statesexhibit fourfold topological degeneracy. On a finite cylinder we have found adramatic even-odd effect depending on the circumference, and propose that thiscan be used as a numerical diagnostic of gapped spin-liquid phases, moregenerally.
