Taming non-equilibrium quantum systems

Final Report Summary - TAQ (Taming non-equilibrium quantum systems)

This project has set out to tackle some of the most intriguing and challenging questions in theoretical physics, related to the behaviour of quantum many-body systems out of equilibrium. After all, statistical physics refers to equilibrium states and properties captures by canonical ensembles. Such equilibrium states are entirely alien to the microscopic laws quantum mechanics that describes how systems would actually evolve in time. This project has successfully set out to understand some of the foundational and conceptual questions related to bringing these seemingly incompatible pictures together. At the same time, using a highly interdisciplinary portfolio of methods ranging from quantum many-body theory to signal processing, it has made technological advances exploiting properties of non-equilibrium. This portfolio of conceptual insights is reflected by an enormously productive publication level.
