Ultracold interactions between ions and polar molecules — •Leon Karpa — Leibniz Universität Hannover, Institut für Quantenoptik, Welfengarten 1, 30167 Hannover, Germany

Ultracold molecules stand out as a promising candidate in a broad spectrum of advanced applications including quantum chemistry, fundamental physics, quantum simulations and information science. Studies of neutral molecular quantum gases and ultracold ion-neutral interactions are two largely complementary interdisciplinary fields that nonetheless share the vision of understanding molecular systems of ever-increasing complexity, and ultimately controlling their properties. In my talk, I will discuss recent advances and challenges in these research domains and how methods from both fields can be used to combine atomic ions with quantum gases of polar molecules. The resulting complex yet precisely controllable system exhibits a hierarchy of tunable attractive and repulsive interactions of different scales, enabling a range of novel experiments and applications. This includes studies of dynamical properties of ultracold polar molecules, ion-molecule collisions in the quantum dominated regime, and the potential formation of ion-molecule many-body bound states.
