Entanglement and topological phases in low-dimensional quantum magnets

Einladung zum Physikalischen Kolloquium im Sommersemester 2017

Quantum magnetic materials are fascinating systems with a multitude of quantum phases of matter. Due to their intrinsic strong interactions, correlation effects and quantum mechanical entanglement are key features. Certain systems, like spin-1 antiferromagnets, show topological phases, whose theoretical discovery was awarded by the Nobel prize in physics in 2016. In my talk, I will review various quantum magnetic systems ranging from lowdimensional materials to quantum simulators for topological phases in systems of ultracold polar molecules on optical lattices, giving an outlook to experimental investigations.
