title: Limit on lorentz and CPT violation of the neutron using a two-species noble-Gas maser
abstract: A search for sidereal variations in the frequency difference between co-located 129Xe and 3He Zeeman masers sets the most stringent limit to date on leading-order Lorentz and CPT violation involving the neutron, consistent with no effect at the level of 10(-31) GeV.
