Arne’s main research interest is in the coherent quantum dynamics of ultracold atomic gases. Specifically, Arne’s group focuses on ultracold spin-changing collisions in sodium spinor Bose-Einstein condensates (BEC). This research has applications in creating massive entanglement useful for quantum computing and in demonstrating new types of matter-wave quantum optics devices such as a phase-sensitive amplifier for atom number measurements. Arne is also interested in long-range interactions between ultracold sodium Rydberg atoms, with applications in precision measurements, quantum-assisted sensing, quantum computing and quantum simulation.
