Conductivity dependent Fizeau’s light dragging effect in a moving sodium like medium

The complex conductivity dependent absorption, dispersion, refractive index, phase velocity and Fizeau's light dragging coefficients are investigated in this article. The refractive index linearly enhances with the amplitude of complex conductivity. The value of refractive index is enhanced from 1.35 to 15 as amplitude of complex conductivity |σ| varies from 20S/m to 5000S/m. The phase velocity has an inverse relation with the refractive index nr. The value of phase velocity decreases from 3×108 m/s to 2×107 m/s as |σ| varies from 20S/m to 5000S/m. A large Fizeau's dragging coefficient is observed at conductivity phase ϕc=π. It is investigated that the Fizeau's dragging coefficient increases or decreases exponentially as a function of control fields Rabi frequencies. The phase shift give peaks at different values of probe detuning and slowly decreases with increasing the amplitude of complex conductivity.
