Etats collectifs dans les semiconducteurs
We explore a broad variety of quantum collective states, from nuclear and electronic spins to indirect excitons and polaritons, and investigate their collective dynamics, correlations, elementary excitations and phase transitions. Compared to their constituting individual particles (spins, excitons, polaritons), these collective states are shaped by particle-particle interactions, quantum statistics, and/or connections with a reservoir. They may be driven into exotic equilibrium states, or strongly out-of-equilibrium schemes. We have developed a broad variety of non-linear spectroscopy techniques, and hyperspectral imaging, allowing us to access their spatial and temporal dynamics.
