Quantum condensed matter: magnetism, superconductivity and beyond
Some of the spectacular properties of solids like complex magnetic order or superconductivity are due to electronic correlations. They are characterised by various competing interactions, for example in low-dimensional materials and multiferroic nanostructures. These classes of materials may be relevant for future technologies like spintronics.
To characterise new physical properties on every relevant time, length, and energy scale and to continuously develop instruments and methods needed for this characterisation.
