Optical Kerr coefficient as function of probe detuning Δ
with two different QD-MF coupling strengths. The inset shows the result for the normal electrons in the nanowire that couple to the QD at the coupling strength ζ=0.03 GHz. The parameters used are Γ1=0.3 GHz, Γ2=0.15 GHz, η=0, γ
=4×10-5 GHz, ω
=1.2 GHz, κMF=0.1 MHz, GHz2, ΔMF=-0.5 GHz, and Δpu=0.5 GHz.
