Laser fluence-dependent production of molecular thorium ions in different charge states for trapped-ion experiments
Jonas Stricker, Jean Velten, Valerii Andriushkov +8
Thorium ions and molecules, recognized for their distinctive nuclear and atomic attributes, are central to numerous trapped-ion experiments globally. Our study introduces an effect…
Improved constraints on exotic interactions between electron and proton in hydrogen
Lei Cong, Filip Ficek, Pavel Fadeev +1
Atomic spectroscopy can be used to search for new bosons that carry exotic forces between elementary fermions. A comparison of a recent precise measurement [Bullis \textit{et al.},…
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. AltuntaÅ et al. Phys. Rev. Lett. 120, 142501 (2018)] is reinterpreted with electronic struct…
Searching for Exotic Interactions between Antimatter
Lei Cong, Filip Ficek, Pavel Fadeev +2
We show that atomic antimatter spectroscopy can be used to search for new bosons that carry spin-dependent exotic forces between antifermions. A comparison of a recent precise meas…
