Description

Lorentz violation has been a popular topic in recent year in the search for experimental signals beyond known physics. We build the general Lorentz-violating terms in the context of effective field theory and analyze measurements in different gravity potentials, comparisons of gravitational accelerations, interferometer experiments, and studies of neutron gravitational bound states to extract first constraints on certain coefficients for Lorentz violation and spin-gravity couplings.
