Abstract: Ultralight bosonic dark matter has come under increasing scrutiny as a dark matter candidate that has the potential to resolve puzzles in astronomical observation. I demonstrate that high-precision measurements of time variation in the frequency ratios of atomic transitions achieve leading sensitivity to ultralight vector portal dark matter at low masses. These bounds are the first laboratory-based bounds on this class of dark matter models. I discuss further measurements that could enhance sensitivity to ultralight dark photons.
Theory Colloquia (formerly CTQM Seminars) will be held in-person on Fridays at 11 am in Duane G126.

The Physics Frontiers Centers (PFC) program supports university-based centers and institutes where the collective efforts of a larger group of individuals can enable transformational advances in the most promising research areas. The program is designed to foster major breakthroughs at the intellectual frontiers of physics by providing needed resources such as combinations of talents, skills, disciplines, and/or specialized infrastructure, not usually available to individual investigators or small groups, in an environment in which the collective efforts of the larger group can be shown to be seminal to promoting significant progress in the science and the education of students. PFCs also include creative, substantive activities aimed at enhancing education, broadening participation of traditionally underrepresented groups, and outreach to the scientific community and general public.
