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…
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…
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.},…
Constraints on Spin-Spin-Velocity-Dependent Interaction
Wei Ji, Weipeng Li, Pavel Fadeev +5
The existence of exotic spin-dependent forces may shine light on new physics beyond the Standard Model. We utilize two iron shielded SmCo electron-spin sources and two opticall…
Limits on axions and axionlike particles within the axion window using a spin-based amplifier
Yuanhong Wang, Haowen Su, Min Jiang +9
Searches for the axion and axionlike particles may hold the key to unlocking some of the deepest puzzles about our universe, such as dark matter and dark energy. Here we use the re…
Cold Atoms in Space: Community Workshop Summary and Proposed Road-Map
Ivan Alonso, Cristiano Alpigiani, Brett Altschul +246
We summarize the discussions at a virtual Community Workshop on Cold Atoms in Space concerning the status of cold atom technologies, the prospective scientific and societal opportu…
Effects of variation of the fine structure constant and quark mass in Mössbauer nuclear transitions
Pavel Fadeev, Julian C. Berengut, Victor V. Flambaum
High accuracy measurements in Mössbauer transitions open up the possibility to use them in the search for temporal and spatial variation of the fine-structure constant , quark m…
Search for exotic spin-dependent interactions with a spin-based amplifier
Haowen Su, Yuanhong Wang, Min Jiang +5
Development of new techniques to search for particles beyond the standard model is crucial for understanding the ultraviolet completion of particle physics. Several hypothetical pa…
Ferromagnetic Gyroscopes for Tests of Fundamental Physics
Pavel Fadeev, Chris Timberlake, Tao Wang +6
A ferromagnetic gyroscope (FG) is a ferromagnet whose angular momentum is dominated by electron spin polarization and that will precess under the action of an external torque, such…
Sensitivity of Th nuclear clock transition to variation of the fine-structure constant
Pavel Fadeev, Julian C. Berengut, Victor V. Flambaum
Peik and Tamm [Europhys. Lett. 61, 181 (2003)] proposed a nuclear clock based on the isomeric transition between the ground state and the first excited state of thorium-229. This t…
Gravity Probe Spin: Prospects for measuring general-relativistic precession of intrinsic spin using a ferromagnetic gyroscope
Pavel Fadeev, Tao Wang, Y. B. Band +4
An experimental test at the intersection of quantum physics and general relativity is proposed: measurement of relativistic frame dragging and geodetic precession using intrinsic s…
Pseudovector and pseudoscalar spin-dependent interactions in atoms
Pavel Fadeev, Filip Ficek, Mikhail G. Kozlov +2
Hitherto unknown elementary particles can be searched for with atomic spectroscopy. We conduct such a search using a potential that results from the longitudinal polarization of a…
Time reversal invariance violation in neutron-nucleus scattering
Pavel Fadeev, Victor V. Flambaum
Planning and interpretation of the experiments searching for the time reversal (T) and parity (P) violation in neutron reactions require values of the matrix elements of the T,P-vi…
Revisiting spin-dependent forces mediated by new bosons: Potentials in the coordinate-space representation for macroscopic- and atomic-scale experiments
Pavel Fadeev, Yevgeny V. Stadnik, Filip Ficek +3
The exchange of spin-0 or spin-1 bosons between fermions or spin-polarised macroscopic objects gives rise to various spin-dependent potentials. We derive the coordinate-space non-r…
Constraints on exotic spin-dependent interactions between matter and antimatter from antiprotonic helium spectroscopy
Filip Ficek, Pavel Fadeev, Victor V. Flambaum +4
Heretofore undiscovered spin-0 or spin-1 bosons can mediate exotic spin-dependent interactions between standard-model particles. Here we carry out the first search for semileptonic…
