The Doppler Effect and Carnet's Principle [PDF]
Nature, 1914 IN my letter of March 19 I endeavoured to show that the latent heat absorbed in the production of unit volume of stationary vibration of a particular frequency in a mixed beam of radiation, is not equal to 4q/c (where q is the energy stream per sq. cm.

Observation of the Zero Doppler Effect. [PDF]
Sci Rep, 2016 AbstractThe normal Doppler effect has well-established applications in many areas of science and technology. Recently, a few experimental demonstrations of the inverse Doppler effect have begun to appear in negative-index metamaterials. Here we report an experimental observation of the zero Doppler effect, that is, no frequency shift irrespective of ...

Relativistic Doppler effect in quantum communication [PDF]
, 2002 When an electromagnetic signal propagates in vacuo, a polarization detector cannot be rigorously perpendicular to the wave vector because of diffraction effects. The vacuum behaves as a noisy channel, even if the detectors are perfect.

Missing Transverse-Doppler Effect in Time-Dilation Experiments with High-Speed Ions [PDF]
, 2010 Recent experiments with high-speed ions have investigated potential deviations from the time-dilation predicted by special relativity (SR). The main contribution of this article is to show that the SR predictions are matched by the experimental results ...

Post-Newtonian Theory for Precision Doppler Measurements of Binary Star Orbits [PDF]
, 1999 The determination of velocities of stars from precise Doppler measurements is described here using relativistic theory of astronomical reference frames so as to determine the Keplerian and post-Keplerian parameters of binary systems.

Measurement-based analysis of delay-Doppler characteristics in an indoor environment [PDF]
, 2016 An analysis of delay-Doppler characteristics in the presence of moving people is presented for short-range communication in an indoor environment. Channel-sounding measurements have been carried out at 3.6 GHz in a crowded university hall during several ...

Theory of Dicke narrowing in coherent population trapping [PDF]
, 2007 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.
