Research Interests

Theoretical Condensed Matter

I study the theoretical physics of quantum many-particle systems in which interactions are qualitatively important and lead to novel behavior. Examples of the systems I am interested in include Bose-Einstein condensates and paired fermion superfluidity, that are phenomena from the realm of ultracold atoms, as well as condensed-matter systems such as graphene (a one-atom thick layer of carbon with interesting electronic properties), heavy-fermion materials, and high-temperature superconductors.
