Ross J. Jennings, Jay D. Tasson, and Shun Yang
TL;DR
This paper explores how violations of local Lorentz invariance in matter sectors can be detected through orbital perturbations in binary pulsar systems, offering sensitivities far surpassing current solar system and laboratory tests.
Contribution
It demonstrates that pulsar data analysis can significantly improve constraints on matter-sector Lorentz violation compared to existing tests.
Findings
Pulsar systems are highly sensitive to Lorentz violation effects.
Binary pulsar data can surpass solar system tests by several orders of magnitude.
The study provides a new method for testing fundamental symmetries in strong gravity.
Abstract
Violations of local Lorentz invariance in the gravitationally coupled matter sector have yet to be sought in strong-gravity systems. We present the implications of matter-sector Lorentz violation for orbital perturbations in pulsar systems and show that the analysis of pulsar data can provide sensitivities to these effects that exceed the current reach of solar system and laboratory tests by several orders of magnitude.
