Work supported by EU projects (SCALA, COMPASS), DFG Munich-Centre for Advanced Photonics, and Spanish MECWe introduce a simple setup corresponding to the matter-wave analogue of impurity atoms embedded in a photonic crystal and interacting with the radiation field. Atoms in a given internal level are trapped in an optical lattice, and play the role of the impurities. Atoms in an untrapped level play the role of the radiation field. The interaction is mediated by means of lasers that couple those levels. By tuning the lasers parameters, it is possible to drive the system through different regimes, and observe phenomena such as matter-wave superradiance, non-Markovian atom emission, and the appearance of bound atomic states.spajournal articlehttp://doi.org/10.1103/PhysRevLett.101.260404https://journals.aps.orgopen access53Photonic band-gapUltracold atomsLocalizationPhysicsEdgeFísica (Física)22 Física
