A Levitated-Magnet Vector Force Sensor for Spin-Dependent Exotic Interactions
Dorian W. P. Amaral, Lei Cong, Tim M. Fuchs +2
We present a magnetically levitated ferromagnetic vector force sensor that enables selective searches for spin-dependent exotic interactions mediated by beyond-Standard-Model boson…

A tunable feedback-controlled magnetic trap for a magnet in free fall
Changhao Xu, Alexander Heidt, Mohammadreza Nematollahi +5
Ferromagnets in free space are predicted to exhibit pure Larmor precession at near-zero magnetic fields and provide exceptional sensitivity for magnetometry and gyroscopy. Notably,…

Testing Exotic Electron-Electron Interactions with the Helium Ionization-Energy Anomaly
Lei Cong, Filip Ficek, Rinat Abdullin +2
Precision atomic spectroscopy provides a sensitive probe of physics beyond the Standard Model. A recently reported theory-experiment discrepancy in the ionization energy of m…
