摘要：
Topological semimetal is a 3D topological state of matter, in which the energy bands touch at a finite number of Weyl nodes. Topological semimetals host paired monopoles of Berry curvature in momentum space, topologically-protected Fermi arcs, and chiral anomaly. These novel properties have inspired many experiments to explore the quantum transport in topological semimetals. I will cover several of our recent works on the quantum transport in topological semimetals, including weak (anti-)localization [1-3] and negative magnetoresistance [4-7], anomalous Shubnikov-de Haas oscillation [8,9], Weyl node annihilation [10], and 3D quantum Hall effect [11].
