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…
Development and Application of an eV Neutron Polarization for Parity Violation Studies at CSNS Back-n Beamline
Xu Qin, Tianhao Wang, Xuanbo Chen +26
The dynamic enhancement of symmetry-breaking effects in neutron-nucleus resonances provides a sensitive testing ground for Time-Reversal Invariance Violation (TRIV). Exploiting thi…
New Upper Bounds on Exotic Neutron Spin-Electron Spin Interactions via Neutron Spin Rotation Measurements in a Compensated Ferrimagnet
T. Mulkey, K. N. Lopez, C. D. Hughes +16
We report a search for exotic spin-spin interactions between neutrons and electrons which could signal new physics beyond the Standard Model using slow neutron polarimetric imaging…
Polarized Neutron Measurements of the Internal Magnetization of a Ferrimagnet Across its Compensation Temperature
C. D. Hughes, K. N. Lopez, T. Mulkey +15
We present the first polarized neutron transmission image of a model Neel ferrimagnetic material, polycrystalline terbium iron garnet (Tb3Fe5O12, TbIG for short), as it is taken th…
