New Laboratory Probes for Low-Mass Dark Matter and Dark Bosons — •Yevgeny Stadnik¹ and Victor Flambaum² — ¹Johannes Gutenberg University of Mainz, Germany — ²University of New South Wales, Australia

Low-mass bosonic dark matter particles produced after the Big Bang may form an oscillating classical field, which can be sought for in a variety of low-energy laboratory experiments based on spectroscopic, interferometric and magnetometric techniques. Dark bosons can also mediate anomalous fifth forces between ordinary-matter particles that can be sought for in laboratory experiments. Recent measurements in atoms and astrophysical phenomena have already allowed us to improve on existing constraints on various non-gravitational interactions between dark bosons and ordinary-matter particles by many orders of magnitude.
