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 me…
Search for a parity-violating long-range spin-dependent interaction
Xing Heng, Zitong Xu, Xiaofei Huang +6
High-sensitivity quantum sensors are a promising tool for experimental searches for beyond-Standard-Model interactions. Here, we demonstrate an atomic comagnetometer operating unde…
Levitated Sensor for Magnetometry in Ambient Environment
Wei Ji, Changhao Xu, Guofeng Qu +1
Levitated particle systems have gained significant attention as a rapidly advancing platform for precision sensing, offering low-loss, highly isolated environments by eliminating m…
Constraints on new vector boson mediated electron-nucleus interactions from spectroscopy of polar diatomic molecules
Konstantin Gaul, Lei Cong, Dmitry Budker
A measurement of parity violation in the hyperfine structure of BaF [E. Altuntaş et al. Phys. Rev. Lett. 120, 142501 (2018)] is reinterpreted with electronic structu…
