Talk with Ms. Wickenbrock on March 27th

Topic: Searching for dark matter with table-top experiments

The nature of dark matter, the invisible substance making up over 4/5 of the matter in
the Universe, is one of the most fundamental mysteries of modern physics.
Ultralight bosons such as axions, axion-like particles or dark photons could make up most
of the dark matter.


Couplings between such bosons and nuclear spins may enable their direct detection via
nuclear magnetic resonance (NMR) spectroscopy: as nuclear spins move through the
galactic dark-matter halo, they couple to dark-matter particles and behave as if they were
in an oscillating magnetic field, generating a dark-matter-driven NMR signal.


I will discuss ways of detecting dark matter with atomic physics machines, present the
Cosmic Axion Spin Precession Experiment (CASPEr) and its results in 2019 and talk about
recent progress of the Global Network of Optically Pumped Magnetometers for Exotic
Physics search (GNOME).


Arne Wickenbrock from Johannes Gutenberg-Universität Mainz will talk on the topic of 'Searching for dark matter with table-top experiments' on the 27st of March, 15:30 at the Hörsaal of the Atominstitut at Stadionallee 2, 1020 Wien.
