Накратко на български

Взаимодействието на светлината с редици от охладени атоми, уловени около оптично нановолокно, се анализира чрез нови теоретични модели. Това помага за разбирането на квантовата памет и начина, по който атомите разсейват светлината.

Optical lattices around a nanofiber waveguide

The NanoArray project realized at Laboratoire Kastler Brossel in Paris aimed at developing a theoretical framework for light scattering in arrays of cold multi-level atoms trapped in the vicinity of an optical nanofiber, in parallel with ongoing experiments at the host. Three overall objectives were pursed and obtained. The first one was the development of an ab-initio microscopic description of light interaction with one-dimensional arrays of atoms trapped in the vicinity of an optical nanofiber, where not only the atom-atom interactions through the nanofiber and free-space modes were taken into account but also the complex vector structure of light and the multi-level structure of the atoms. Using the developed formalism it was then possible to explain experimental results on atomic Bragg scattering and highly-efficient quantum memory implementation. The developed formalism finally allowed to study the emergence of subradiance in a periodic lattice with a specific period close to a quarter of the resonant atomic wavelength.

Цел на проекта

Recently developed experimental techniques for cooling, trapping and localizing atoms near nanostructures, such as one-dimensional nanoscopic waveguides, offer a new paradigm to investigate quantum light-matter interactions. Collective coherent effects in such engineered interfaces pave the way to integrated quantum technology applications, including single-photon sources and efficient quantum memory for light. The present project investigates this approach based on arrays of cold atoms trapped in the vicinity of a nanofiber. In parallel to experimental developments at the host, this project will develop the theoretical framework of photon scattering in commensurate and non-commensurate arrays and will include ab-initio microscopic description of the interaction. Bragg scattering and superradiance effect will be studied to obtain larger efficiency than previous ensemble-based implementations. Waveguide-mediated long-range organization of the array will also be investigated.
