报告摘要：The manipulation of particle transport in synthetic quantum matter is an active research frontier. In this presentation, I will introduce our recent efforts in harnessing chiral currents in ultracold atoms with synthetic gauge field, by employing the interplay with Floquet engineering and contact interaction. I will mainly focus on our experimental demonstration of engineered topological transport in a synthetic flat-band lattice of ultracold atoms. Besides, I will briefly introduce a theoretical viewpoint toward the switch of chiral currents with contact interaction if time permits.
