Title:Double-dimers and lattice symplectic fermions
Abstract:
We consider double-dimers in bounded subgraphs of \Z^2 and construct thereon pairs of (discrete symplectic) fermions as random variables. From those, we build —via a Sugawara construction on the fermion modes— a Virasoro representation on the space of local fields with central charge c=-2 .
