Strongly Interacting Many-Body Systems

The realization and the control of long range interactions with atomic systems at very low temperatures opened up a whole new realm of many-body physics that has become a central focus of research. Atomic systems with long-range interactions can be realized with Rydberg atoms, magnetic atoms and polar molecules. Nowadays they find applications to the simulation of quantum phases of matter, metrology, quantum communication and information. Our objective is the study of these platforms in connection to current experiments.
