Precise Lifetime Measurement of the Cesium State
S. Pucher, P. Schneeweiss, A. Rauschenbeutel +1
We measure the lifetime of the cesium state using a time-resolved single-photon-counting method. We excite atoms in a hot vapor cell via an electric quadrupole transit…
Shelving spectroscopy of the strontium intercombination line
I. Manai, A. Molineri, C. Fréjaville +8
We present a spectroscopy scheme for the 7-kHz-wide 689-nm intercombination line of strontium. We rely on shelving detection, where electrons are first excited to a metastable stat…
Observation of the algebraic localization-delocalization transition in a 1D disordered potential with a bias force
G. Berthet, L. Lavoine, M. Parit +3
In a one-dimensional (1D) disordered potential, quantum interferences leading to Anderson lo-calization are ubiquitous, such that all wave-functions are exponentially localized. Mo…
Three-dimensional trapping of individual Rydberg atoms in ponderomotive bottle beam traps
Daniel Barredo, Vincent Lienhard, Pascal Scholl +4
We demonstrate three-dimensional trapping of individual Rydberg atoms in holographic optical bottle beam traps. Starting with cold, ground-state Rb atoms held in standard op…
Near-resonant light scattering by a sub-wavelength ensemble of identical atoms
N. J. Schilder, C. Sauvan, Y. R. P. Sortais +2
We study theoretically the scattering of light by an ensemble of resonant atoms in a sub-wavelength volume. We consider the low intensity regime so that each atom responds line…
Measurement of the atom-surface van der Waals interaction by transmission spectroscopy in a wedged nano-cell
T. Peyrot, N. Šibalić, Y. R. P. Sortais +5
We demonstrate a method for measuring atom-surface interactions using transmission spectroscopy of thermal vapors confined in a wedged nano-cell. The wedged shape of the cell allow…
