Dimensional Control of the Coherence Time of Scattered Light in Cold Atom Clouds
Ana Cipris, Mateus a F Biscassi, J C C Capella +9
Cold atomic clouds are promising platforms for generating correlated photons, but multiple scattering and associated Doppler broadening limit their temporal coherence. Here we demo…
Lifetime measurement of the 5s5p 1P1 state in strontium
Ivana Puljić, Ana Cipriš, Damir Aumiler +2
We present a direct lifetime measurement of the state of strontium using time-correlated single-photon counting of laser induced fluorescence in a hot atomic beam. To…
Phase-contrast imaging of a dense atomic cloud
M. Frometa Fernandez, P. G. Santos Dias, P. H. Nantes Magnani +5
We present the experimental production and characterization of a dense cold atomic cloud of \(^{88}\text{Sr}\) atoms, optimized for the future studies of light transport in highly…
Photonic bands and normal mode splitting in optical lattices interacting with cavities
Philippe Wilhelm Courteille, Dalila Rivero, Gustavo Henrique de França +5
Strong collective interaction of atoms with an optical cavity causes normal mode splitting of the cavity's resonances, whose width is given by the collective coupling strength. At…
Absolute frequency measurement of the 5s5p - 5s5d transition in strontium
Ana Cipriš, Ivana Puljić, Damir Aumiler +2
We report on the absolute frequency determination of the 5s5p - 5s5d transition in atomic strontium, achieved through frequency comb-referenced laser-induced-fluore…
Optical interpretation of linear-optics superradiance and subradiance
S. Asselie, A. Cipris, W. Guerin
Super- and subradiance are usually described in the framework of Dicke collective states, which is an ``atomic picture'' in which the electromagnetic field only provides an effecti…
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…
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…
Intensity fluctuations signature of 3D Anderson localization of light
Florent Cottier, Ana Cipris, Romain Bachelard +1
Apart from the difficulty of producing highly scattering samples, a major challenge in the observation of Anderson localization of 3D light is identifying an unambiguous signature…
