  • 24.10.2017 Markus Heyl (MPIPKS Dresden) Dynamical quantum phase transitions

The theory of phase transitions plays a central role for the understanding of equilibrium physical systems. In this talk I will introduce a dynamical analogue, termed dynamical quantum phase transitions, occuring during nonequilibium quantum real-time evolution. I will summarize the recent achieved advances including the first experimental observations in ultracold atoms as well as trapped ions. Furthermore, I will discuss to which extent important concepts of equilibrium criticality can be generalized to these dynamical transitions. In particular, I will show that it is possible to extend the concepts of scaling and universality by considering the specific example of the Ising model.
