Insights into coherently controlled Fizeau light dragging in five-level atomic medium

Le résumé fourni par la source

Abstract We address the coherent regulation of Fizeau's light dragging effect in a five-level atomic medium using the exploitation of joint strong control and weak probing fields. The strength of Fizeau's light dragging, as well as the phase velocity and group index, exhibit a strong reliance upon the detuning of the probing type field and the associated Rabi type frequencies of the control fields. The maximum coefficient for Fizeau's light dragging is determined to be ± 500. This phenomenon significantly affects the phase along with the group velocities and induces a phase shift in light pulses propagating through the medium. Besides, the phase shift with maximum strength of light pulse in the medium is found to be ± 0.08 radians. Finally, it is important to note that our findings hold practical implications for applications such as interferometry, imaging coding, and the development of cloaking devices.
