Superradiance as single scattering embedded in an effective medium
P. Weiss, A. Cipris, R. Kaiser +2
We present an optical picture of linear-optics superradiance, based on a single scattering event embedded in a dispersive effective medium composed by the other atoms. This linear-…
Subradiance with saturated atoms: population enhancement of the long-lived states
A. Cipris, N. A. Moreira, T. S. do Espirito Santo +5
Dipole-dipole interactions are at the origin of long-lived collective atomic states, often called subradiant, which are explored for their potential use in novel photonic devices o…
Collective Excitation Dynamics of a Cold Atom Cloud
T. S. do Espirito Santo, P. Weiss, A. Cipris +4
We study the time-dependent response of a cold atom cloud illuminated by a laser beam immediately after the light is switched on experimentally and theoretically. We show that coop…
Collective Multi-mode Vacuum Rabi Splitting
W. Guerin, T. S. do Espirito Santo, P. Weiss +4
We report the experimental observation of collective multi-mode vacuum Rabi splitting in free space. In contrast to optical cavities, the atoms couple to a continuum of modes, and…
Robustness of Dicke subradiance against thermal decoherence
P. Weiss, A. Cipris, M. O. Araújo +2
Subradiance is the cooperative inhibition of the radiation by several emitters coupled to the same electromagnetic modes. It was predicted by Dicke in 1954 and only recently observ…
Subradiance and radiation trapping in cold atoms
Patrizia Weiss, Michelle O. Araújo, Robin Kaiser +1
We experimentally and numerically study the temporal dynamics of light scattered by large clouds of cold atoms after the exciting laser is switched off in the low intensity (linear…
