TL;DR: In this article, the search for the electric-dipole moment (EDM) of laser-cooled francium (Fr) atoms could lead to a measurement for the electron EDM.

TL;DR: It is demonstrated that at lower CW light intensities vacuum conditions are not perturbed by the photodesorption and hence the MOT dynamics remains unaffected, while the trap population increases thanks to the incoming desorbed atoms flux.

TL;DR: The existence of a non-zero electric dipole moment (EDM) implies the violation of time reversal symmetry as mentioned in this paper, and the existence of EDM implies new physics beyond the SM.
