The research on condensed matter theory at the University of Alabama reflects the broad spectrum of topics and phenomena that is characteristic of modern condensed matter physics. Interests of our faculty range from fundamental questions related to collective behavior and transport in solid state systems to the study of novel materials and device designs that may shape future technologies.
Our faculty and their current research interests are:
- Georg Schwiete – Theoretical condensed matter physics, in particular transport and dynamics in quantum many-body systems. We are especially interested in the combined effects of disorder and interactions in low-dimensional systems. The two-dimensional electron liquid near the metal-insulator transition or disordered superconducting films near the transition to the superconducting state are prominent examples of systems where these effects become particularly strong and lead to qualitatively new phenomena. We are also engaged in research on systems with strong spin-orbit coupling such as topological insulators and in aspects of magnetism and spintronics. Most of our studies are based on methods of quantum field theory in condensed matter physics.
- Wang-Kong Tse – Theoretical condensed matter physics, in particular the physics of transport, light-matter interaction and many-body effects in low-dimensional quantum materials and structures. Our research is focused on unraveling the properties of novel materials through a combination of analytical and numerical techniques in quantum field theory and materials modeling. Some recent systems we are interested in include graphene and graphene-like systems, 2D transition-metal dichalcogenides, topological insulators, and materials with spin-orbit coupling that host unconventional and tunable properties.
- Sanjoy Sarker (retired, emeritus) – Theoretical condensed matter physics, in particular strongly correlated systems, high Tc superconductivity and complex order. We are engaged in theoretical research on highly correlated electron systems, such as the high-temperature cuprate superconductors and rare-earth-transition metal-oxides, and quantum liquids. Our work seeks a theoretical understanding of unusual properties of these systems, caused by a delicate interplay between the charge and the spin degrees of freedom, based on the Hubbard and the related t-J and Anderson models. We are particularly interested in the breakdown of Fermi liquid theory, and the appearance of complex magnetic and structural order and associated metal insulator transitions in many strongly correlated materials.
