The Casimir–Polder force between atoms or molecules and is of quantum mechanical origin and forms the basis of quantum friction, which is predicted to occur when two objects move at distance on the order of nanometers relative to each other. In this presentation, we consider the effects of this force on the energy levels of atoms and their velocity dependence as well as that of the resulting transition frequencies [1]. We propose to investigate this frequency dependence in the experiments of M. Ducloy and M. Fichet [2] by measuring the changes in the reflection coefficients of a modulated laser beam incident on the boundary between a dielectric and a gas of moving atoms.
