We shall present our recent investigations on cooperatively induced and enhanced interactions in photon or phonon superradiance processes evolving in an ensemble of initially excited two- or three-level real or artificial atomiclike quantum emitters embedded on a vibrating membrane. Initially, we will discuss a scheme which is able to create subradiant and entangled two-qubit states.Then we shall demonstrate that an ensemble of two-level excited emitters can significantly increase the oscillation amplitude of the vibrating membrane containing the ensemble via superradiance-like effects. Involving various quantum interference effects occurring in cooperatively interacting ensembles, ultraweak atomic transitions are shown to be highly enhanced.
