Research Interests

My research interests are mainly concerned with quantum systems that exhibit strong electronic correlations. High-temperature cuprate superconductors, Mott insulators, heavy fermions are famous solid-state compounds in this family. The electronic interactions that these materials are subject to induce exciting physical phenomena but also represent a formidable theoretical challenge where standard well-established tools are not able to provide systematic and reliable results. In order to push forward the frontiers of our understanding it is therefore necessary to resolutely develop novel theoretical frameworks and my research activity aims at finding minimal models that are simple enough that their solution can be found accurately, and that reproduce the phenomenology of strongly-correlated systems. Because the lack of powerful numerical methods often represents a bottleneck in the analysis of such theoretical models, I am also working on the development of new algorithms that can handle the increasing complexity of the systems that are considered. The physical compounds that I am currently most interested in are cuprate superconductors and heavy fermions. In addition, cold atomic systems represent a promising setup to emulate and test theoretical ideas.
