Axions, axion-like particles (ALPs), dilatons, and other ultralight (masses from 10^-4 down to 10^-22 eV) particles have been discussed as possible candidates for dark matter. An interesting feature of these ideas is that they lead to predictions of potentially observable transient and oscillating effects. I will describe how we are looking for these as well as the relation of such experiments to tests of fundamental symmetries (P, CP, T, CPT ...)
