Condensed Matter Theory

Our research covers wide areas of condensed and soft matter physics, including superconductivity, magnetism, low-dimensional systems, quantum mesoscopic phenomena, topological matter, nonequilibrium and driven systems, and active self-assembled materials.

We place strong emphasis on collaboration with various experimental programs at Argonne. Our long-term goals are to make fundamental advances in condensed matter and materials physics as it relates to DOE Basic Energy Sciences mission goals. Our primary research thrusts involve: high-temperature and topological superconductors; transition metal compounds with novel properties (such as quantum spin liquids and charge/spin density waves); superconductor-superinsulator transitions; topological properties of metallic and nanostructured magnets and topological excitations in mesoscopic systems; quantum phase transitions in strongly correlated electron systems; transport in quantum wires, quantum dots, and spintronic devices; optimization of transport properties of superconductors by large-scale simulations; magnetization textures and dynamics in nanostructured magnetic systems; quantum thermodynamics and irreversibility; and fundamental interactions in active self-assembled systems.
