报告简介：Klein tunneling refers to the quantum tunneling effect of relativistic particles when they meet a high potential step or barrier. Although not observed in particle physics due to the difficulty of generating a huge electric or gravitational potential, it has been observed in graphene which hosts massless Dirac fermions. In this talk, I will introduce two novel effects related to Klein tunneling. One is called spin-nonconserving Klein tunneling, during which process the effective spin of quasiparticles is not conserved. The other is the Klein tunneling of Weyl magnons, which could affect the magnetotransport of magnetic systems. The concept of Klein tunneling, originated ninety years ago, still shines to physical researches nowadays.
