TL;DR
This paper reports on an experiment using a 3He/129Xe co-magnetometer to test Lorentz symmetry, providing new bounds on background fields interacting with neutron spins.
Contribution
The study introduces a novel experimental setup with updated measurements that improve constraints on Lorentz symmetry violations.
Findings
Background field interaction with neutron spin constrained to b_n < 3.72 x 10^(-32) GeV
Experimental setup demonstrates sensitivity to Lorentz symmetry violations
Preliminary results set new limits on Lorentz-violating background fields
Abstract
To test Lorentz symmetry we used a 3He/129Xe co-magnetometer. We will give a short summary of our experimental setup and the results of our latest measurements. We obtained preliminary results for the equatorial component of the background field interacting with the spin of the bound neutron: b_n < 3.72 x 10^(-32) GeV (95 C.L.).
