The Migdal effect and applications to dark matter searches

Atoms can be ionized by the interaction of a photon with one of the electrons in the atomic orbitals. As pointed out by Migdal in 1939, atoms could also be ionized by the interaction of a neutron with the atomic nucleus.  This process has been revisited recently in the context of dark matter detection. The most common strategy for dark matter detection is the search for nuclear recoils induced by dark matter interactions with the nucleus. However, the Migdal effect could also induce the ionization of the atom, leading to additional (sometimes unique) dark matter signals. In this bachelor thesis the student will calculate the probability of ionization of an atom due to the Migdal effect, and will analyze the implications for dark matter searches.
