Abstract
En 中文
This work investigates the photonic spin hall shift is controlled within a dielectric medium influenced by the Kerr nonlinearity effect. The incoming light beams interacts with cavity that contains four-level atomic system. The spin hall shift is tuned to exhibit positive or negative values, depending on the parameters of applied driving fields. The spin hall shift reaches its peak value of +/- 57.2 lambda <=alpha pL,R <=+/- 58 lambda\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$ \pm 57.2\lambda \le \alpha <^>{L,R}_{p} \le \pm 58\lambda $$\end{document}, when influenced by the Rabi frequency of the control field (zeta 2\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\zeta _{2}$$\end{document}= 8 Gamma\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\Gamma $$\end{document} and 50 Gamma\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\Gamma $$\end{document}).
