Synthetic-gauge-field stabilization of the chiral-spin-liquid phase
Abstract
We calculate the phase diagram of the SU(N Hubbard model describing fermionic alkaline earth atoms in a square optical lattice with on-average one atom per site, using a slave-rotor mean-field approximation. We find that the chiral spin liquid predicted for N\ge5and large interactions passes through a fractionalized state with a spinon Fermi surface as interactions are decreased before transitioning to a weakly interacting metal. We also...
