摘      要：We propose a scheme to realize the SU(3)spin-orbit coupled three-component fermions in an one-dimensional optical *** topological properties of the single-particle Hamiltonian are studied by calculating the Berry phase,winding number and edge *** also investigate the effects of the interaction on the ground-state topology of the system,and characterize the interaction-induced topological phase transitions,using a state-of-the-art density-matrix renormalization-group numerical ***,we show the typical features of the emerging quantum phases,and map out the many-body phase diagram between the interaction and the Zeeman *** results establish a way for exploring novel quantum physics induced by the SOC with SU(N)symmetry.
