Drift waves and instabilities in ultracold plasmas — •Cornelia Lechner, Christian Knapp, and Alexander Kendl — Institut für Ionenphysik und Angewandte Physik, Universität Innsbruck, Technikerstraße 25, A-6020 Innsbruck, Austria

Ultracold quasi-neutral plasmas merge the physics of strongly coupled plasmas and of ultracold quantum gases. Recent experiments have been reported on first observations of ultracold plasma waves and instabilities, which are counterparts of well-known drift instabilities in hot plasmas (where they are e.g. responsible for turbulent transport losses in fusion experiments). However, not much attention has yet been devoted to the theory of ultracold plasma instabilities. Here, we present an analysis of possible theoretical approaches to ultracold plasmas, and discuss the influence of strong Coulomb coupling on the drift dynamics of such systems, especially concentrating on the case of a magnetized ultracold plasma.
