  • Abstract Stimulated by recent experimental realization of tunability of multi-particle processes in ultracold fermion gases, we study a SO(4) symmetric generalized Hubbard model in an one-dimensional lattice with two-body and three-body interactions up to the nearest neighboring sites. By using the bosonization and renormalization-group schemes, we focus on weak-coupling regime and half-filled band, and determine the ground-state phase diagram, which consists of the Mott-insulator (MI… CONTINUE READING
