Transition metal oxide surfaces and interfaces, twisted bilayer graphene and dichalcogenide bilayers host emergent electronic states arising from an interplay of crystal structure, kinetics, Coulomb interactions, orbital specialization and spin-orbit contributions. These confined systems can be driven across insulator to metal or to superconductor transitions, and in some cases large magneto-resistive or spin fluctuation regimes. Topological properties are also expected for several materials. The scope of the school is to present the theoretical approaches and experimental tools allowing us to capture the physics at play for these emergent states. Spintronics and oxide electronics applications will also be discussed.
