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…
Limit on Lorentz-Invariance- and CPT-Violating Neutron Spin Interactions Using a He-Xe Comagnetometer
Fabian Allmendinger, Ulrich Schmidt, Werner Heil +2
We performed a search for a Lorentz-invariance- and CPT-violating coupling of the He and Xe nuclear spins to posited background fields. Our experimental approach is to…
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…
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…
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…
Ultra-sensitive magnetometry based on free precession of nuclear spins
C. Gemmel, W. Heil, K. Lenz +11
We discuss the design and performance of a very sensitive low-field magnetometer based on the detection of free spin precession of gaseous, nuclear polarized 3He or 129Xe samples w…
