Van der Waals dephasing for Dicke subradiance in cold atomic clouds

Ana Cipris, Romain Bachelard, Robin Kaiser +1

We investigate numerically the role of near-field dipole-dipole interactions on the late emission dynamics of large disordered cold atomic samples driven by a weak field. Previous…

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…

Instability threshold in a large balanced magneto-optical trap

Marius Gaudesius, Robin Kaiser, Guillaume Labeyrie +2

Large clouds of cold atoms prepared in a magneto-optical trap can develop spatio-temporal instabilities when the frequency of the trapping lasers is brought close to the atomic res…

Connecting field and intensity correlations: the Siegert relation and how to test it

Dilleys Ferreira, Romain Bachelard, William Guerin +2

The Siegert relation relates the electric field and intensity correlations of light, under given assumptions. After a brief history of intensity correlations, we give a derivation…
