My main research interests lie in the study of strongly correlated electronic systems. These are materials where the interactions between electrons play a crucial role and lead to novel phenomena not explainable by single electron band structure effects. Examples include the Mott insulators, spin liquids, and topological insulators. By using numerical methods, like classical and quantum Monte Carlo, exact diagonalization, density-matrix renormalization group, and analytic approaches (slave particles, Gutzwiller approximation, and spin waves), I focused my attention on Hubbard-like models and their generalizations.
