Algebraic liquid phase with soft graviton excitations
Feb, 2006Citations per year
Abstract: (arXiv)
Models which spontaneously generate graviton gauge symmetry are discussed. In 2 dimensional space the dual version of this model is similar to the RK point action in quantum dimer model, and certain vertex operator drives the system into crystalized phase. In 3 dimensional space this model is self-dual, and algebraic liquid phase is protected from developing any crystal order or superfluid order by gauge symmetry in both sides of the duality. The liquid phase has collective excitation with the same gauge symmetry and polarization of graviton. However the graviton excitation has soft dispersion relation , and spin-spin correlation function falls algebraically. Topological order of the spin liquid is also discussed. 18 winding numbers are required to specify one topological sector.- 75.10.Jm
