Abstract
Topological semimetal is a 3D topological state of matter, in which the conduction and valence bands touch at a finite number of Weyl nodes. Topological semimetals host "monopoles" of the Berry curvature in momentum space, topologically-protected Fermi arcs, and probably the chiral anomaly, thus have inspired many experiments to explore the quantum transport in them. I will cover our recent works on the quantum transport in topological semimetals, including a 3D quantum Hall effect, weak anti-localization, negative magnetoresistance, Shubnikov-de Haas oscillation, etc.
Coffee and tea will be served 20 minutes prior to the seminar.
Anyone interested is welcome to attend.
