Torsion and Nonmetricity Constraints From Neutron Spin Rotation in Polarized Matter
Sepehr Samiei, Ralf Lehnert, W. Michael Snow
Many modified-gravity frameworks employ non-Riemannian connection degrees of freedom, including torsion and nonmetricity. In Einstein-Cartan-type theories, torsion is associated wi…

Cryogenic Penning-Trap Apparatus for Precision Experiments with Sympathetically Cooled (anti)protons
M. Niemann, T. Meiners, J. Mielke +17
Current precision experiments with single (anti)protons to test CPT symmetry progress at a rapid pace, but are complicated by the need to cool particles to sub-thermal energies. We…

Constraining Spacetime Nonmetricity with Neutron Spin Rotation in Liquid He-4
Ralf Lehnert, W. M. Snow, Zhi Xiao +1
General spacetime nonmetricity coupled to neutrons is studied. In this context, it is shown that certain nonmetricity components can generate a rotation of the neutron's spin. Avai…
