Manipulation of the photonic spin hall shift using the four levels atomic system

This study explores the coherent control of the photonic spin hall shift through a configuration involving a four-levels dielectric medium. The probe beam engages with a cavity containing a four-level dielectric medium. By adjusting the parameters of the driving fields, the photonic spin shift can be controlled to exhibit either positive or negative values. The maximum values of the spin hall shift is in the range of [Formula: see text] with the incidence angle ([Formula: see text]= 1.2 radian and 3 radian ) and the minimum values is reported as [Formula: see text] against the probe field detuning ([Formula: see text] and [Formula: see text]). The results hold significant potential for use in fields like sensing devices, spin-based electronics, magnetic storage and quantum information processing.
