Panel (a) describes ΔI₁ for exchange splitting between ψ₂ and ψ₁ being 4J_⊥ = 1 (black line), 0.1 (red line), 0.01 (green line), and 0.001(blue line) meV. Panel (b) describes ΔI₁ (black line), ΔI₂ (red line), and ΔI₃ (green line) for meV. Panel (c) describes the carrier density and the reduction of the exchange as a function of the intensity of excitation light. Panel (d) plots ΔI₁ as a function of magnetic field with 4J_⊥ = 1 meV for intensities of 0.34 (black line) and 0.85 W/cm² (red line). Black and red dots are the corresponding experimental values in ref. 12. Panels (e,f) illustrate the Δg and Σg mechanisms. The exciton relaxation time is fixed at 10⁻¹⁰ s.
