Local Lorentz Invariance (LI) is a postulate of today's theories of the fundamental interactions. Theoretical work towards a unified theory suggests that LI may only be an approximate symmetry. This motivates experimental tests of LI with increased sensitivity. One aspect of LI is isotropy, the independence of the results of any local experiment from its orientation in space. We report on the results of a strongly improved test of the isotropy of light propagation (Michelson-Morley-type… Expand

Tests of Lorentz Invariance
Tests of Lorentz invariance have been performed in wide variety of fields since Einstein’s special relativity was formulated more than 100 years ago. In this chapter, we will review previous tests ofExpand
Direct terrestrial test of Lorentz symmetry in electrodynamics to 10−18
This work uses ultrastable oscillator frequency sources to perform a modern Michelson–Morley experiment and makes the most precise direct terrestrial test to date of Lorentz symmetry for the photon, constraining LorentZ violating orientation-dependent relative frequency changes. Expand

Generalized bumblebee models and Lorentz-violating electrodynamics
The breaking of Lorentz symmetry via a dynamical mechanism, with a tensor field which takes on a nonzero expectation value in vacuum, has been a subject of significant research activity in recentExpand
Michelson–Morley analogue for electrons using trapped ions to test Lorentz symmetry
Assuming that Lorentz symmetry holds for electrons and that the photon dispersion relation governs the Coulomb force, a fivefold-improved limit on anisotropies in the speed of light is obtained. Expand
The experiment of Michelson and Morley
Light was assumed to propagate in a medium called ether which was all pervading and stationary. Earth’s motion through ether was expected to have an effect on the velocity of light in the directionExpand
Physics in a general length space-time geometry: Call for experimental revision of the light speed anisotropy
We present a phenomenological model for the nature in the Finsler and Randers space-time geometries. We show that the parity-odd light speed anisotropy perpendicular to the gravitationalExpand
Lorentz and CPT violation in the Standard-Model Extension
Lorentz and CPT invariance are among the symmetries that can be investigated with ultrahigh precision in subatomic physics. Being spacetime symmetries, Lorentz and CPT invariance can be violated byExpand
High-sensitivity crossed-resonator laser apparatus for improved tests of Lorentz invariance and of space-time fluctuations
We describe an improved Michelson-Morley-type laser apparatus for highly sensitive tests of Lorentz invariance in the electron and photon sectors. The realization of an ultrastable rotation tableExpand
Testing Lorentz invariance using an asymetric optical resonator
Recent experiments utilizing resonant cavities have produced remarkable results that limit the level of any possible violation of Lorentz Invariance. However, within the framework of the StandardExpand
