From: Floquet engineering of anomalous Hall effects in monolayer MoS2
a, b The Berry curvature Ω|v,↑〉, Ω|c,↑〉, Ω|v,↓〉, and Ω|c,↓〉 contributed by the valence and conduction parts of the spin-up and spin-down bands with increasing laser amplitude A0 for photon energy ℏω = 1.7 eV. The black dots represent the values for the valence bands, while red dots correspond to the conduction bands, as indicated on the right axis. The blue dashed lines are guide to the eye. c, d The Berry curvature Ω|↑〉 and Ω|↓〉 of the total spin-up and spin-down bands for ℏω = 1.7 eV and ℏω = 1.9 eV. e, f Schematic illustration depicting the valley and spin Hall effects under LPL for ℏω = 1.7 eV and ℏω = 1.9 eV. The transparent balls represent the electrons that have disappeared under the influence of light.
