The project evolves around the concept of topological phases in condensed matter physics, with a focus on topological semimetals, whose theory has had a steep development in the past decade with the discovery of materials like graphene, topological insulators, and Weyl/Dirac semimetals. Focus will be given to the latter exotic electromagnetic response, in particular in the THz electromagnetic spectral region. The goal of the project will be the study of specific nonlinear effects predicted theoretically in the physics of Weyl semimetals. Fundamental research on topological semimetals optical responses and their possible practical applications will be discussed, along with the interest of opening such a research line at Sapienza University.
