Spin-precession method for sensitive electric dipole moment searches

Abstract

In the context of searches for a nonzero permanent electric dipole moment (EDM), a spin-precession method is demonstrated which provides a high sensitivity to experimental parameters such as electric-field strength and employed laser intensity while maintaining sensitivity to an EDM. This approach allows for constraining systematic biases as a necessary step towards an increased sensitivity in probing physics beyond the Standard Model through stringent EDM limits.
