Summary: This study presents the first experimental realization of an atom-optically synthetic gauge field based on the synthetic momentum-state lattice. By tuning the interacting lattice into a noninteracting regime using magnetically controlled Feshbach resonance, the flux-dependent populations of atoms and the gauge field-induced chiral currents in a two-leg ladder structure are observed. The study also demonstrates the control of atomic transport in the ladder using an inhomogeneous gauge field.
