The Maximum Doppler Effect [PDF]
The maximum numerical values of the Doppler coefficient of a single Breit Wigner resonance and the dilutions for which the stationary values occur have been found as a function of temperature. The results are tabulated in terms of parameters which are independent of the particular resonance and model.

Theory of Dicke narrowing in coherent population trapping [PDF]
The Doppler effect is one of the dominant broadening mechanisms in thermal vapor spectroscopy. For two-photon transitions one would naively expect the Doppler effect to cause a residual broadening, proportional to the wave-vector difference.

Rotational Doppler effect in left-handed materials
We explain the rotational Doppler effect associated with light beams carrying with orbital angular momentum in left-handed materials (LHMs). We demonstrate that the rotational Doppler effect in LHMs is unreversed, which is significantly different from ...

Comment on ''Inverse Doppler shift and control field as coherence generators for the stability in superluminal light'' [PDF]
In their study of inverse Doppler shift and superluminal light [Phys. Rev. A 91, 053807 (2015)], Ghafoor et al. consider a three-level atomic arrangement with transitions in the optical domain.

Christian Doppler and the Doppler effect
A summary is given of Doppler's life and career. He was born 180 years ago on November 29, 1803, in Salzburg, Austria. He died on March 17, 1853 in Venice. The effect bearing his name was first announced in a presentation before the Royal Bohemian Society of the Sciences in Prague on May 25, 1842.
