Theoretical Condensed Matter
Professor Garg's research centers around quantum phenomena involving the orientational degree of freedom of spin angular momentum. Current projects include the formalism of spin coherent-state path integrals and spin semiclassics, and the collective relaxational dynamics of spins in molecular solids of single-molecule magnets.
Professor Koch's research focuses on the theory of interacting photons in circuit QED arrays, their nonequilibrium steady-states, dissipative phase transitions, open-system quantum simulation, and on new mechanisms for enhancing quantum coherence in superconducting qubits by intrinsic quantum error protection.
James A. Sauls
Professor Sauls' research is focused on phases of condensed matter that derive from spontaneous symmetry breaking and topological order, including topological phases of superfluid 3He and unconventional superconductors. Sauls' research group is working towards an understanding of transport via edge and surface states of topological superconductors and superfluid3He.
