Motivated by ideas about quantum gravity, a tremendous amount of effort over the past
decade has gone into testing Lorentz invariance in various regimes. This review …

Einstein's general theory of relativity is the standard theory of gravity, especially where the
needs of astronomy, astrophysics, cosmology and fundamental physics are concerned. As …

Because classical Maxwellian electromagnetism has been one of the cornerstones of
physics during the past century, experimental tests of its foundations are always of …

Time dilation is one of the most fascinating aspects of special relativity as it abolishes the
notion of absolute time. It was first observed experimentally by Ives and Stilwell in 1938 …

We report on a new experiment that tests for a violation of Lorentz invariance (LI), by
searching for a dependence of atomic transition frequencies on the orientation of the spin of …

In theories with broken Lorentz symmetry, Čerenkov radiation may be possible even in
vacuum. We analyze the Čerenkov emissions that are associated with the least constrained …

The research reactor TRIGA Mainz is an ideal facility to provide neutron-rich nuclides with
production rates sufficiently large for mass spectrometric and laser spectroscopic studies …

Einstein's general theory of relativity is the standard theory of gravity, especially where the
needs of astronomy, astrophysics, cosmology, and fundamental physics are concerned. As …

We present the first results from a rotating Michelson-Morley experiment that uses two
orthogonally orientated cryogenic sapphire resonator oscillators operating in whispering …

We summarise the scientific and technological aspects of the Search for Anomalous
Gravitation using Atomic Sensors (SAGAS) project, submitted to ESA in June 2007 in …
