Helicity-dependent photocurrents in the chiral Weyl semimetal RhSi

Weyl semimetals are crystals in which electron bands cross at isolated points in momentum space. Associated with each crossing point (or Weyl node) is an integer topological...

外尔半金属（Weyl semimetals）是一类电子能带在动量空间的孤立点处发生交叉的晶体。每一个该类交叉点（或称外尔节点，Weyl node）均关联有一个整数拓扑……
