Our group investigates few-body problems and their role in a many-body context. Of particular interest are low-dimensional systems and strong interactions. Using different approaches ranging from considering exactly solvable models to numerical simulation methods, the group studies static and dynamic structures in systems that can be realised using cold atoms, cold molecules or trapped ions. For example, the group investigates the quantum dynamics of strongly interacting cold atoms and their potential for realising quantum spin transistors and to perform quantum simulations of so-called lattice gauge theories. With their clear AMO physics context, the developed theoretical proposals are well aligned with the experimental activities of the Center.
