Superconductors provide energy transport without loss due to vanishing electrical resistance below a certain temperature. Concerning technological applications the so-called high-temperature superconductors are particularly interesting as their critical temperature can be reached by cooling with liquid nitrogen. However, up to now the mechanisms underlying this phenomenon are not fully understood. Quantum simulators as realized by scientists from the “Quantum Many-Body Systems Division” promise to bring more insight. more
Complex quantum systems can order in a wide range of different ways. While order in conventional matter can be explained from local properties of the system, strongly correlated systems exhibit so-called topological order, where the quantum correlations of the system, termed entanglement, organize globally. Yet, methods from Quantum Information Theory allow model the entanglement structure of these systems locally and thus open up a plethora of applications in the study and classification of topologically ordered systems. more
