Condensed Matter Physics is the study of the immense variety of solids and liquids provided by nature or made by humans. Metals, magnets, ceramics, semiconductors, foams, membranes, superfluids, superconductors, granular systems, polymers, complex liquids, planetary interiors, and graphene are examples of the sorts of things we work on. Of particular importance are functional and nanostructured materials. The section consists of two highly collaborative groups, Experimental Solid State Physics and Condensed Matter Theory . In addition to fundamental research, together these two groups address a number of key challenges in science such as energy and efficient energy use; security, sensors and nanomagnetism; research at the interface with biomedical sciences; functional materials and metamaterials for nanoelectronics and nanophotonics, and plastic electronics.
