摘要：
Topological matter exhibits novel transport properties due to the topological and geometrical nature of the Bloch states, one of which examples is the widely studied Berry curvature. Recently, it has been shown that nonlinear transport reveals significant quantum geometric effect in addition to Berry curvature. I will give an overview of the recent progress in this field, followed by our work on the nonlinear photocurrent in topological semimetals. Moreover, by virtue of the rapid development of quantum technology, quantum processors offer a playground for simulations. I will talk about the quantum simulation of topological quench dynamics on quantum processors. Lastly, future directions on the interplay between nonlinear transport, quantum geometry and quantum simulations will be addressed.
