Abstract
Many materials with complex structure and composition are known to host intriguingemergent electronic phenomena. An enlarged number of degrees of freedom andthe presence of strong interactions impose a conceptual challenge for their description.The lack of a clear theoretical understanding of their phenomenology impedes thecommunity to design new efficient routes for the optimization of functional propertiesin these systems. This proposal aims to bridge the microscopic and phenomenologicaldescription of the physics in complex materials, with focus on superconductivityin strongly correlated systems, and to explore the recent experimental developmentsin materials fabrication, control in ultrafast time scales, and also in cold atoms platformsin order to propose new ways to improve materials and investigate novel phasesof matter. The theoretical approaches proposed here build on recent developmentsin the area of unconventional superconductivity, with the introduction of the idea ofsuperconducting fitness, and on generalizations of large-N techniques including newconcepts such as supersymmetry and symplectic extensions of symmetry groups. Thedevelopment of new theoretical frameworks for the description of complex systemswill fundamentally advance our understanding and guide the engineering of the nextgeneration of quantum materials for technological applications.
