Test of Lorentz Symmetry by using a 3He/129Xe Co-Magnetometer
K. Tullney, C. Gemmel, W. Heil +11
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 prelimi…
Precise Measurement of Magnetic Field Gradients from Free Spin Precession Signals of He and Xe Magnetometers
F. Allmendinger, P. Blümler, M. Doll +12
We report on precise measurements of magnetic field gradients extracted from transverse relaxation rates of precessing spin samples. The experimental approach is based on the free…
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…
Using a rotating magnetic guiding field for the 3He-129Xe-Comagnetometer
F. Allmendinger, U. Schmidt, W. Heil +5
Our search for non-magnetic spin-dependent interactions is based on the measurement of free precession of nuclear spin polarized 3He and 129Xe atoms in a homogeneous magnetic guidi…
Limit on Lorentz and CPT violation of the bound Neutron Using a Free Precession 3He/129Xe co-magnetometer
C. Gemmel, W. Heil, S. Karpuk +11
We report on the search for Lorentz violating sidereal variations of the frequency difference of co-located spin-species while the Earth and hence the laboratory reference frame ro…
Probing Physics beyond the Standard Model with He/Xe clock comparison experiments
U. Schmidt, F. Allmendinger, W. Heil +5
The comparison of the free precession of co-located 3He-129Xe spins (clock comparison) enables us to search for very tiny nonmagnetic spin interactions. With our setup we could est…
