Preparation of one-dimensional chains and dense cold atomic clouds with a high numerical aperture four-lens system Open
We report the efficient and fast (∼2Hz) preparation of randomly loaded one-dimensional (1D) chains of individual 87Rb atoms and of dense atomic clouds trapped in optical tweezers using an upgraded experimental platform. This platform is de…

Near-Resonant Light Scattering by a Subwavelength Ensemble of Identical Atoms Open
We study theoretically the scattering of light by an ensemble of N resonant atoms in a subwavelength volume. We consider the low intensity regime so that each atom responds linearly to the field. While N noninteracting atoms would scatter …

Measurement of the atom-surface van der Waals interaction by transmission spectroscopy in a wedged nanocell Open
We demonstrate a method for measuring atom-surface interactions using transmission spectroscopy of thermal vapors confined in a wedged nanocell. The wedged shape of the cell allows complementary measurements of both the bulk atomic vapor a…

Fabrication and characterization of super-polished wedged borosilicate nano-cells Open
We report on the fabrication of an all-glass vapor cell with a thickness varying linearly between (exactly) 0 and ∼1 μm. The cell is made in Borofloat glass that allows state-of-the-art super polish roughness, a full optical bonding assemb…

Optical Transmission of an Atomic Vapor in the Mesoscopic Regime Open
By measuring the transmission of near-resonant light through an atomic vapor confined in a nanocell we demonstrate a mesoscopic optical response arising from the nonlocality induced by the motion of atoms with a phase coherence length larg…

Collective Lamb Shift of a Nanoscale Atomic Vapor Layer within a Sapphire Cavity Open
We measure the near-resonant transmission of light through a dense medium of potassium vapor confined in a cell with nanometer thickness in order to investigate the origin and validity of the collective Lamb shift. A complete model includi…

Propagation of light through small clouds of cold interacting atoms Open
We demonstrate experimentally that a cloud of cold atoms with a size\ncomparable to the wavelength of light can induce large group delays on a laser\npulse when the laser is tightly focused on it and is close to an atomic\nresonance. Delay…
