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…
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…
Constraints on Spin-Dependent Short-Range Interaction between Nucleons
Kathlynne Tullney, Fabian Allmendinger, Martin Burghoff +10
We report on the search for a new spin-dependent P- and T-violating interaction between nucleons mediated by light, pseudoscalar bosons such as the axion which was invented to solv…
