Degaussing Procedure and Performance Enhancement by Low-Frequency Shaking of a 3-Layer Magnetically Shielded Room

Fabian Allmendinger, Benjamin Brauneis, Werner Heil +1

We report on the performance of a Magnetically Shielded Room (MSR) intended for next level He/Xe co-magnetometer experiments which require improved magnetic conditions.…

Measurement of the Permanent Electric Dipole Moment of the Xe Atom

F. Allmendinger, I. Engin, W. Heil +7

We report on a new measurement of the CP-violating permanent Electric Dipole Moment (EDM) of the neutral Xe atom. Our experimental approach is based on the detection of the…

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…

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…
