Second-harmonic generation in the topological multifold semimetal RhSi
Recent experiments in the topological Weyl semimetal TaAs have observed record-breaking second-harmonic generation (SHG), a nonlinear optical response at 2ω generated by an incoming light source at ω. However, whether SHG is enhanced in topological semimetals in general is a challenging open questio...
