Condensed Matter Theoretical Physics
Superconductivity is associated with magnetic flux expulsion, which in turn causes magnetic levitation in the above demonstration (see video). J. Robert Schrieffer was the co-recipient of the Nobel Prize for developing the BCS theory of superconductivity.
Our group maintains active theoretical research programs at the forefront of both "hard" and "soft" condensed matter physics. The former strives to understand phenomena arising from interplay of quantum mechanics and interactions among an extremely large number of constituents. On the other hand, the latter studies states of matter dominated by energies of the order of room temperature where quantum aspects are generally unimportant. Nevertheless, condensation of matter into complex yet organized collective states is a common theme unifying the two subfields
Examples "hard" theory are studies of
- high-temperature superconductors (Manousakis, Vafek, Yang)
- heavy Fermion systems (Dobrosavljevic, Schlottmann)
- glassy and complex behavior of correlated systems (Dobrosavljevic)
- metal-insulator transitions (Dobrosavljevic)
- one-dimensional electron system (Schlottmann, Yang)
- quantum computation (Bonesteel)
- quantum criticality (Bonesteel, Dobrosavljevic, Manousakis, Schlottmann,Vafek, Yang)
- quantum Hall effects (Bonesteel, Manousakis, Vafek, Yang)
- quantum liquids and solids (Manousakis)
- transition metal oxides (Dobrosavljevic, Schlottmann)
Examples of "soft" theory are studies of
- equilibrium and nonequilibrium computational statistical mechanics (Rikvold)
- Biological systems (Rikvold)
