Cooperative quantum behavior occurs naturally in dense ensembles of quantum emitters, where strong particle-particle interactions, such as near field dipole-dipole exchanges can compete with the collective coupling to confined bosonic optical modes. We develop theoretical methods, based on master equations and quantum Langevin equations, applicable to systems ranging from pure quantum emitters subject to disorder and decoherence to molecular ensembles where coupling of electrons to vibrons and phonons pose important challenges. Among others, we aim at specific applications in quantum information, quantum metrology and vacuum-modified material properties such as exciton, energy or charge transport.
