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…
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. AltuntaÅ et al. Phys. Rev. Lett. 120, 142501 (2018)] is reinterpreted with electronic struct…
New Constraints on Axion Mediated Dipole-Dipole Interactions
Zitong Xu, Xing Heng, Guoqing Tian +5
The search for axions sits at the intersection of solving critical problems in fundamental physics, including the strong CP problem in QCD, uncovering the nature of dark matter, an…
Ultralight dark matter detection with levitated ferromagnets
Saarik Kalia, Dmitry Budker, Derek F. Jackson Kimball +7
Levitated ferromagnets act as ultraprecise magnetometers, which can exhibit high quality factors due to their excellent isolation from the environment. These instruments can be uti…
Spin-dependent exotic interactions
Lei Cong, Wei Ji, Pavel Fadeev +8
Novel interactions beyond the four known fundamental forces in nature (electromagnetic, gravitational, strong and weak interactions), may arise due to "new physics" beyond the stan…
Constraining Ultralight Dark Matter through an Accelerated Resonant Search
Zitong Xu, Xiaolin Ma, Kai Wei +9
Experiments aimed at detecting ultralight dark matter typically rely on resonant effects, which are sensitive to the dark matter mass that matches the resonance frequency. In this…
