The Fresnel-Fizeau effect of transverse drag, in which the trajectory of a light beam changes due to the 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 3.6Γ—105, corresponding to the ratio between the light speed in vacuum and the group velocity under EIT conditions. We study the…

Light-Drag Enhancement by a Highly Dispersive Rubidium Vapor.
It is shown experimentally that the observed drag effect can be enhanced by over 2 orders of magnitude when the light beam propagates through a moving slow-light medium.
Large Fizeau's light-dragging effect in a moving electromagnetically induced transparent medium
With a large enhancement of the dragging effect, this work realizes an atom-based velocimeter that has a sensitivity two orders of magnitude higher than the velocity width of the atomic medium used and could pave the way for motional sensing using the collective state of atoms in a room temperature vapour cell or solid state material.
Evidence of slow-light effects from rotary drag of structured beams
Self-pumped slow light, typically observed within laser gain media, is created by an intense pump field. By observing the rotation of a structured laser beam upon transmission through a spinning ruby…

A light beam normally incident upon an uniformly moving dielectric medium is, in general, subject to bendings due to a transverse Fresnel-Fizeau light drag effect. In most familiar dielectrics, the…

Rotary Photon Drag Enhanced by a Slow-Light Medium
This result shows that rotary photon drag applies to images as well as polarization, and the possibility of switching between different rotation states may offer new opportunities for controlled image coding.
Observation of light dragging in a rubidium vapor cell.
It is found that the minimum group velocity is achieved for light redshifted from the center of the atomic resonance and that the value of this shift increases with decreasing group velocity, in agreement with the theoretical predictions by Kocharovskaya, Rostovtsev, and Scully.
