Testing Lorentz invariance using an odd-parity asymmetric optical resonator

Tests of Lorentz invariance using a microwave resonator.

The frequencies of a cryogenic sapphire oscillator and a hydrogen maser are compared to set new constraints on a possible violation of Lorentz invariance. We determine the variation of the oscillator frequency as a function of its orientation (Michelson-Morley test) and of its velocity (Kennedy-Thorndike test) with respect to a preferred frame candidate. We constrain the corresponding parameter...

Rotating Resonator-Oscillator Experiments to Test Lorentz Invariance in Electrodynamics

Testing Lorentz Invariance using Atmospheric Neutrinos and AMANDA-II

Several phenomenological models of physics beyond the Standard Model predict flavor mixing in the neutrino sector in addition to conventional mass-induced oscillations. In particular, violation of Lorentz invariance (VLI) results in neutrino oscillation effects parametrized by the maximal attainable velocity difference δc/c. We report on a study of the sensitivity of the AMANDA-II detector to s...

Testing Lorentz and CPT Invariance with Neutrinos

Neutrino experiments can be considered sensitive tools to test Lorentz and CPT invariance. Taking advantage of the great variety of neutrino experiments, including neutrino oscillations, weak decays, and astrophysical neutrinos, the generic experimental signatures of the breakdown of these fundamental symmetries in the neutrino sector are presented.

Experimental Design for Testing Local Lorentz Invariance Violations in Gravity

Local Lorentz invariance is an important component of General Relativity. Testing for Local Lorentz invariance can not only probe the foundation stone of General Relativity but also help to explore the unified theory for General Relativity and quantum mechanics. In this paper, we search the Local Lorentz invariance violation associated with operators of mass dimension d = 6 in the pure-gravity ...
