El grupo de Física de los Sistemas Complejos les invita a asistir al siguiente seminario. Ponente: Prof. Beatriz Olmos, University of Tübingen. Titulo: „Collective coupling of an array of atoms near a nanofiber“ Abstract: In this talk, I will summarize some of the latest results we have published in our group on a light-matter system composed of emitters coupled to light modes which propagate in a waveguide. This setup is subject matter of many current experimental studies, as it holds promise of applications in quantum information routing and processing, e.g., as optical isolators and circulators where the light is emitted unidirectionally, or as generators of entangled atomic and photonic states. Among other results, I will show you how due to the collective light-matter interaction with the radiation field, an array of atoms can scatter light from an external laser field almost exclusively into one of the guided modes of the waveguide, allowing for almost lossless and completely unidirectional channelling of photons. Moreover, I will show you that the spectral properties of the scattered light depend strongly on the angle of incidence of the laser field on the array and the dispersive interactions between the light and the atoms, uncovering a modified Bragg condition.
