I am studying strongly correlated many-body systems, particularly in the ambit of condensed matter physics. This involves the application of numerical methodologies going beyond the mean-field treatment with the goal of uncovering quantum phases of matter which may be of interest for material science applications.
On the example of the two dimensional Hubbard model and immediate extensions, I have been working on the development and application of both finite size multi-determinant algorithms (selective configuration interaction approaches) and embedding methods (dynamical mean-field theory and its cluster extensions) to study zero temperature phenomena. Recently, I have also started to look at the real time dynamics of these strongly correlated systems.
