A Weyl semimetal TaAs holds surface and bulk states. The different optical response of surface and bulk states was studied under weak and high‐intensity light irradiations. The anisotropic optical properties of different states were studied, including the linear and nonlinear response, which are determined by the relationship and balance between its topological surface states and Weyl nodes. Besides, the mobility can be accelerated by the optical field. (Image: S. Chi et al.; article number 1600359 in this issue).
