The band structure topology is commonly characterized by the Berry curvature, which leads to exotic surface states and anomalous Hall effect. In this talk, I will introduce our recent works on topology-induced nonlinear phenomena, including the nonlinear anomalous Hall effect the photocurrent, and unidirectional magnetoresistance. Here, the topology is discussed in a broader context beyond the Berry curvatu
