New limit on Lorentz and CPT violating neutron spin interactions using a free precession 3He-129Xe co-magnetometer

F. Allmendinger, W. Heil, S. Karpuk +6

We report on the search for a CPT and Lorentz invariance violating coupling of the 3He and 129Xe nuclear spins (each largely determined by a valence neutron) to background tensor f…
