Abstract

The rotary photon drag based on knot bundles is investigated via control fields of the Milnor Gaussian polynomial in a duplicated two-state atomic configuration driven by probe and control fields. The photon drag is a function of wavelength-normalized spatial axes \(x/\lambda\) and \(y/\lambda\). Photon drag is connected to refractive index and group index as \(\theta _d=\frac{L\omega _s}{c}(n_g-\frac{1}{n_r})\). Both anomalous and normal photon drag is investigated in this study. The trefoil knot, Solomon knot, Hopf links, and double Hopf links types of photon drag are observed. The highest value of normal photon drag is investigated to \(\pm 1.5~ \upmu \text {rad}\), and the highest value of anomalous photon drag is reported to \(\pm 0.7~\upmu \text {rad}\) within the spatial region \(-4\lambda \le x, y\le 4\lambda\). The results have important uses in quantum imaging, telecommunication, quantum memory, quantum sensors, optical systems, and photonic circuits.

基于结束的双能级原子介质中正常和异常旋转光子阻力研究
利用米尔诺高斯多项式的控制场研究了在探针场和控制场驱动下的双态原子组态中基于结束的旋转光子拖拽。光子拖拽是波长归一化空间轴的函数 \(x/\lambda\) 和 \(y/\lambda\). 光子拖拽与折射率和群折射率连接为 \(\theta _d=\frac{L\omega _s}{c}(n_g-\frac{1}{n_r})\). 本文研究了异常和正常的光子阻力。观察了三叶草结、索罗门结、霍普夫链和双霍普夫链类型的光子拖拽。研究了法向光子阻力的最大值为 \(\pm 1.5~ \upmu \text {rad}\),异常光子阻力的最大值为 \(\pm 0.7~\upmu \text {rad}\) 在空间区域内 \(-4\lambda \le x, y\le 4\lambda\). 研究结果在量子成像、电信、量子存储、量子传感器、光学系统和光子电路中具有重要的应用。
