Sebastian Will's research group investigates quantum systems of ultracold atoms and molecules. The group cools atoms and molecules to ultracold temperatures just a sliver above absolute zero - reaching the coldest temperatures allowed by nature. Close to absolute zero temperature, the behavior of particles is ultimately determined by the laws of quantum mechanics. Thanks to the precision tools of atomic physics, the group has full control over the quantum state of each particle and the interactions between them. With ultracold gases of atoms and molecules they create new quantum systems and perform quantum simulations of strongly interacting quantum matter. The special focus is the creation and investigation of ultracold molecules that interact via dipolar long-range interactions. Those will allow us to study exotic quantum phases and quantum phase transitions.
