Abstract:
Most of the energy content of universe most likely consists of dark matter and dark energy. The standard model just covers about 5% of it. The search for other than gravitational signatures of dark matter is a very active and vibrant research field. Several proposed theoretical candidates posses weak couplings to standard model particles. Two experiments in Mainz embedded in an international research effort look for pseudo-magnetic couplings of new ultralight bosons to nuclear and electronic spins. The Cosmic Axion Spin Precession experiment (CASPER) and the Global Network of Optically Pumped Magnetometers for Exotic physics searches (GNOME). The first is looking for the expected galactic dark matter background made out of axion-like particles (ALPs), and the latter looks for other topological manifestations of dark matter. I will talk about both and give you an update about the currently ongoing advanced GNOME science run.
