Popis:	Transverse current generation by circularly polarized light in biased matter has attracted considerable attention for studies of Floquet engineering and inverse spin Hall effect. Field-induced circular photogalvanic effect (FI-CPGE) also contributes to the current, but has been overlooked in many literatures. Using terahertz pulses as a bias field, we study the case of a prototypical semiconductor GaAs by two-dimensional Fourier analysis. We demonstrate the remarkable role of FI-CPGE resonantly enhanced near the band degeneracy, suggesting its potential to detect monopoles in momentum space. Our results provide a comprehensive understanding of the light-induced anomalous Hall effect. Comment: 17 pages, 4 figures
