Ultracold Atomic Gases

Atomic physics experiments access ultra-low temperatures where quantum effects are most prominent. I am interested in studying collective quantum phenomena, such as superfluidity and magnetism, in the context of cold atoms.


Graphene, a one-atom thick sheet of carbon, has novel mechanical and electronic properties such as an approximate “relativistic” electronic energy spectrum. I am interested in studying how electron interactions affect observable properties (like the conductivity) of graphene as well as related systems such as topological insulators.

High-temperature Superconductivity

Novel Superconductivity: The conventional "Bardeen-Cooper-Schrieffer" (BCS) theory of superconductors, formulated in 1957, is remarkably successful at describing conventional low-temperature superconductors but fails for numerous modern superconductors, including the cuprate and pnictide high-temperature superconductors but also the exotic "Fulde-Ferrell-Larkin-Ovchinnikov" superconducting state of superconductors in an applied magnetic field. Our group is interested in materials exhibiting such states, and also in cold atomic gas experiments that can realize unconventional superconducting states of cold fermionic atoms.
