  • The CPGE spectrum and optical conductivity in RhSi are measured and discussed, comparing to theoretical predictions. Weyl semimetals are crystals in which electron bands cross at isolated points in momentum space. Associated with each crossing point (or Weyl node) is a topological invariant known as the Berry monopole charge. The circular photogalvanic effect (CPGE), whereby circular polarized light generates a helicity-dependent photocurrent, is a notable example of a macroscopic property that… CONTINUE READING
