Quantum Magnetism - Basic Theory and Relevant Experiments
While magnetism is a purely quantum mechanical phenomenon in itself, quantum phenomena are particularly pronounced and can be directly accessed by experiments in systems with sufficiently small localized spins and reduced effective dimensionality. In these so-called Quantum Magnets the macroscopic behavior is dominated by quantum fluctuations. Quantum magnets reveil exotic ground states and unusual excitations, and long range order may be even completely suppressed by quantum disorder. The lecture will give an introduction to the basics of magnetic spin systems, magnetic interactions and (quantum) phase transitions while the main focus will concern experimental results on low-dimension quantum spin systems. Lecture + Tutorials are associated with 4 CPs.
