Modern Tests of Lorentz Invariance
1Department of Physics, University of California at Davis, Davis, CA 95616 USA.
Researchers are testing Lorentz invariance, a fundamental principle, using new high-precision experiments and astrophysical observations. This review covers theoretical frameworks and experimental progress, presenting current constraints on potential violations.
Area of Science:
- Theoretical physics
- Quantum gravity
- Experimental physics
Background:
- Lorentz invariance is a cornerstone of modern physics.
- Quantum gravity theories suggest potential violations of Lorentz invariance.
- Recent experimental advances enable high-precision tests.
Purpose of the Study:
- To review theoretical frameworks for testing Lorentz invariance.
- To summarize experimental advances enabling precise tests.
- To present current constraints on Lorentz violating effects.
Main Methods:
- Review of theoretical models for Lorentz violation.
- Analysis of experimental techniques for high-precision tests.
- Compilation of astrophysical and terrestrial observational data.
Main Results:
- Established theoretical frameworks for Lorentz invariance tests.
- Detailed experimental progress in achieving high precision.
- Presentation of current stringent constraints on Lorentz violating effects.
Conclusions:
- Lorentz invariance is well-tested across various regimes.
- Experimental and observational efforts continue to refine constraints.
- No significant violations of Lorentz invariance have been detected.
