What’s up in quantum chaos? — •Roland Ketzmerick — Institut für Theoretische Physik, Technische Universität Dresden, 01062 Dresden

Many fundamental quantum signatures of chaos have been established in recent years, partly based on a deeper understanding of classical dynamics. This talk will review some of these highlights, like the universal properties of energy spectra when the classical limit shows fully chaotic dynamics. For typical systems, where regular and chaotic phase-space regions coexist, we can say now whether or not quantum eigenstates will respect these regions and a quantitative understanding of tunneling between them is on the way. Future challenges will be addressed throughout the talk.
