I am a Ph.D. student in the Condensed Matter Theory Group at the Niels Bohr Institute. My research focuses on the theoretical modelling of unconventional superconductors, which are materials that can conduct a current with zero resistance at low temperatures. Specifically, my Ph.D. project involves modelling the material Sr2RuO4, where the main challenge is to propose a superconducting state reconciling with all experimental evidence. Moreover, I am also part of an experimental collaboration focused on the theoretical modelling of interacting electrons in finite grids and artificial networks, which are relevant for arrays of quantum dots. Studying these materials could provide a better understanding and reveal new applications of the exciting phenomenon of superconductivity.
