abstract
We used a torsion pendulum and rotating attractor with 20-pole electron-spin distributions to probe dipole-dipole interactions mediated by exotic pseudo-Goldstone bosons with $m_{\rm b}\leq 500 \; \mu$eV and coupling strengths up to 14 orders of magnitude weaker than electromagnetism. This corresponds to symmetry-breaking scales $F \leq 70$ TeV, the highest reached in any laboratory experiment. We used an attractor with a 20-pole unpolarized mass distribution to improve laboratory bounds on $CP$-violating monopole-dipole interactions with $1.5\:\mu$eV$<m_{\rm b}<400\:\mu$eV by a factor of up to 1000.

Theoretical proposal for a spacecraft-Earth experiment to constrain spin- and velocity-dependent fifth forces mediated by ultralight vector bosons, claiming up to three orders of magnitude improvement over current bounds.
The paper reviews comagnetometry as a sensitive probe for new physics including EDMs, Lorentz violation, CP-violating forces, and axionic dark matter, while discussing prospects for further sensitivity gains based on signal-to-noise.
