论文摘要
横向阻力的菲涅尔 - 旋转效果，其中光束的轨迹由于光学介质的横向运动而变化，通常非常小，难以检测。我们观察到一个移动的热蒸气电池中的横向阻力，利用电磁引起的透明度（EIT）引起的慢光。阻力效应通过360,000的因子增强，对应于真空中的光速与在EIT条件下的组速度之间的比率。我们研究热原子运动的贡献，该运动比平均介质速度要快得多，并确定其对横向阻力的影响可忽略不计的机制。
The Fresnel-Fizeau effect of transverse drag, in which the trajectory of a light beam changes due to transverse motion of the optical medium, is usually extremely small and hard to detect. We observe transverse drag in a moving hot-vapor cell, utilizing slow light due to electromagnetically induced transparency (EIT). The drag effect is enhanced by a factor 360,000, corresponding to the ratio between the light speed in vacuum and the group velocity under EIT conditions. We study the contribution of the thermal atomic motion, which is much faster than the mean medium velocity, and identify the regime where its effect on the transverse drag is negligible.
