Variational cluster approach to superconductivity and magnetism in the Kondo lattice model
Benjamin Lenz, Riccardo Gezzi, Salvatore R. Manmana
We investigate in detail antiferromagnetic (AF) and superconducting (SC) phases as well as their coexistence in the two-dimensional Kondo lattice model on a square lattice, which i…

Functional renormalization group for non-equilibrium quantum many-body problems
R. Gezzi, Th. Pruschke, V. Meden
We extend the concept of the functional renormalization for quantum many-body problems to non-equilibrium situations. Using a suitable generating functional based on the Keldysh ap…
