Title: New Phases of Magnetic Quantum Matter

Materials made of arrays of quantum spins forming well-defined lattices serve as model systems to study the phases of correlated magnetic quantum matter
like spin Luttinger-liquids, magnon Bose-Einstein condensates, or spin super-solids. Neutron and X-ray scattering are unique tools for high-precision studies of such phases and of their correlations and excitations with high energy and momentum resolution. The results will be discussed in the context of recent developments in computational physics and exciting new opportunities that free electron lasers will offer to study the time-dependence and out-of- equilibrium dynamics of such systems.
