Low-frequency divergence of circular photomagnetic effect in topological semimetals
Novel fermions with relativistic linear dispersion can emerge as low-energy excitations in topological semimetal materials.Here, we show that the orbital moment contribution in the circular photomagnetic effect for these topological semimetals exhibit an unconventional ω -1 frequency scaling, leading to significantly enhanced response in the low frequency window, which can …
