Competing charge and spin orders in SU(3) fermionic systems — •Mohsen Hafez-Torbati and Walter Hofstetter — Institute of Theoretical Physics, Goethe University, Frankfurt am Main, Germany
Three-component systems with a full SU(3) symmetry can be simulated using 6Li, alkaline-earth atoms and Yb at large magnetic field where nuclear spin and electronic angular momentum get decoupled. We consider the fermionic SU(3) symmetric Hubbard model on the triangular lattice in the presence of a staggered potential and at the filling of one particle per lattice site. Using real-space dynamical mean-field theory we study the competition between the staggered potential and the Hubbard interaction and reveal the phase diagram of the model. Phases such as band insulator, metallic, Mott insulator with 120∘ spiral order, and charge-ordered Mott insulator are identified.
