Description
In well-motivated extensions of the Standard Model to solve the strong CP problem of quantum chromodynamics, axions emerge as leading candidates of non-WIMP dark matter. In this seminar, we discuss tabletop-scale experiments in axion detection, particularly focusing on new observables for direct detection of axion dark matter. For instance, axion interactions with electrons in condensed matter would produce spin flips in a ferrimagnetic sample (QUAX), or excite the upper Zeeman level of rare earth atoms in suitable rare-earth doped crystalline matrices (AXIOMA). The experimental parameters required to achieve cosmologically relevant sensitivity in both approaches will be briefly discussed.
