We investigate Mössbauer nuclei embedded in nanoscale photonic structures to observe and control the cooperative emission of x-ray photons. We use highly brilliant x-ray sources like synchrotrons and x-ray lasers to study how quantum cooperative phenomena like super- and subradiance evolve from such structures as a function of photon multiplicity. We equally explore how the coupling of collective modes leads to quantum optical phenomena like electromagnetically induced transparency and measurement-induced entanglement. The theoretical description of this novel regime of quantum cooperative light-matter interaction will enable the design of tailor-made radiative properties for future applications in x-ray quantum optics.
