Dissipative light-matter systems can display emergent collective behavior. Here, we report a Z_{2}-symmetry-breaking phase transition in a system of multilevel ^{87}Rb atoms strongly coupled to a weakly driven two-mode optical cavity. In the symmetry

Photon-antibunching in the fluorescence of statistical ensembles of emitters at an optical nanofiber-tip

This proposal investigates the photon-statistics of light emitted by a statistical ensemble of cold atoms excited by the near-field of an optical nanofiber tip. Dipole–dipole interactions of atoms at such short distance from each other suppress the

Despite a long history, light scattering by particles with size comparable with the light wavelength still unveils surprising optical phenomena, and many of them are related to the Fano effect. Originally described in the context of atomic physics, t

Quasi-resonant scattering of light in two dimensions can be described either as a scalar or as a vectorial electromagnetic wave. Performing a scaling analysis we observe in both cases long lived modes, yet only the scalar case exhibits Anderson local

Collective atomic recoil lasing

Autor: Dietmar Kruse, Benjamin Deh, Philippe W. Courteille, Christoph Von Cube, Sebastian Slama, Claus Zimmermann

Publikováno v: Journal of Modern Optics. 51:957-965

A cloud of ultra-cold atoms is loaded into the attractive potential of a light wave that is generated by two counter-propagating modes of a high- finesse ring resonator. The two modes are coupled by the atoms due to coherent Rayleigh scattering and g
