Significance of precision tests of special relativity

Physics Letters A, 1993
Abstract Recent experiments using two-photon absorption and phase comparison of masers can set bounds on Lorentz-violating preferred-frame alternatives to special relativity, but cannot give empirical knowledge concerning the one-way speed of light, since the latter depends on the synchronisation convention.

NEW OPTICAL TESTS OF SPECIAL RELATIVITY

Laser Spectroscopy, 2004
Special Relativity (SR) is a fundamental theory that underlies all established models of the forces of nature, from the gravitational and electromagnetic to the weak and strong nuclear forces. Violations of SR, however, seem to be a common feature of many proposed models of quantum gravity, like string theory and loop gravity.

Modern Optical Tests of Special Relativity

2007 European Conference on Lasers and Electro-Optics and the International Quantum Electronics Conference, 2007
In this paper, the authors give a detailed report on a specific such clock comparison, which can be viewed as a modern descendant of the classical Michelson-Morley experiment testing the isotropy of the speed of light.

Fundamental Tests of Special Relativity and the Isotropy of Space [PDF]

, 1987
When one considers tests of special relativity and the isotropy of space, the experiment of MICHELSON and MORLEY [1] immediately comes to mind. These scientists might not have anticipated that one hundred years after their landmark experiment, there is an ever increasing interest in the subject.

Tests of special relativity using the Doppler effect

Proceedings of the IEEE, 1976
The classical and relativistic Doppler shifts are compared for light incident at any angle upon a perfectly reflecting mirror moving in any arbitrary direction. It is shown that experiments designed to test the theory of special relativity in reflecting systems must be accurate up to third order in v/c.

Critical reviews and tests of the foundations of special relativity [PDF]

Foundations of Physics Letters, 1988
The origin of the equilibrium paradoxes of special relativity is here analysed. We show that static forces, as defined by Hooke's law, do not transform in the same way as the usual dynamical forces, thus giving rise to the paradoxes. This inconsistency justifies the present search for alternative theories such as the modern ether theories. Some crucial

Experimental test of special relativity by laser spectroscopy [PDF]

Hyperfine Interactions, 2006
The Doppler-free laser-spectroscopic frequency measurement of Doppler-shifted optical lines in forward and backward direction of a fast ion beam permits a sensitive test of the relativistic Doppler-formula and, hence, the relativistic time dilation factor γ SR=(1−ν 2/c 2)−1/2.

IMPROVED TESTS OF SPECIAL RELATIVITY VIA LIGHT SPEED ANISOTROPY MEASUREMENT

, 2010
The Mansouri–Sexl theory is a well-known test theory of relativity. In the following paper we demonstrate a novel way of detecting second-order effects in terms of both lab and ion speed for light speed anisotropy detection.

Improved optical test of special relativity

2003 European Quantum Electronics Conference. EQEC 2003 (IEEE Cat No.03TH8665), 2003
A new Michelson-Morley (MM) experiment that is based on a one-year comparison of the frequencies /spl nu//sub x/ and /spl nu//sub y/ of two lasers stabilized to crossed cryogenic optical resonators (CORES) at 1064 nm. The experiment relies on a highly developed laser frequency stabilization scheme: an automatic beam positioning system continuously ...
