Topological Phases of Dipolar Particles in Elongated Wannier Orbitals
Topological Phases of Dipolar Particles in Elongated Wannier Orbitals
We show that topological phases with fractional excitations can occur in two-dimensional ultracold dipolar gases on a particular class of optical lattices. Because of the dipolar interaction and lattice confinement, a quantum dimer model emerges naturally as the effective theory describing the low-energy behaviors of these systems under well-controlled approximations. …
