Spectrum of surface states in a non-centrosymmetric superconductor.

We use Feynman diagrams to evaluate the optical properties of graphene.

Our effort in condensed matter theory covers a wide variety of phenomena in correlated electron systems and superconductivity. We rapidly respond to new developments in the field and maintain close contact with both computational physicists and experimentalists. In recent years the focus of our research has been on unconventional superconductivity including iron-based superconductors, Kondo lattice physics and quantum critical phenomena in heavy fermion materials, properties of graphene, and topological aspects of non-centrosymmetric superconductors. We maintain small to medium size groups where students work in close contact with postdocs and professors at every stage of their projects. Our students learn a wide range of theoretical tools and numerical methods, and acquire a broad understanding of complex phenomena in correlated electronic and magnetic materials. These skills allow them to respond to the most current needs of the field and make significant and lasting contributions. For more details, contact Prof. Ilya Vekhter ( ).
