Sebastian Diehl’s research is located on the interface of quantum optics and many-body physics. In ultracold quantum gases, these areas increasingly merge together. Certain systems call for a description as open many-body systems, in which coherent and dissipative dynamics compete. This concerns natural occurrences of dissipation such as atom loss, but also instances of engineered driven-dissipative dynamics. There, dissipation may not occur as a perturbation, but rather as dominant resource of many-body dynamics, allowing for counter-intuitive effects such as dissipatively induced quantum order. A deeper understanding requires new theoretical tools, which combine concepts of quantum optics with modern field theoretical techniques.
