Rydberg atoms with principal quantum number n⪢ 1 have exaggerated atomic properties
including dipole-dipole interactions that scale as n 4 and radiative lifetimes that scale as n 3 …

Ultracold neutral plasmas formed by photoionizing laser-cooled atoms near the ionization
threshold have electron temperatures in the 1–1000K range and ion temperatures from tens …

We demonstrate coherent optical detection of highly excited Rydberg states (up to n= 124)
using electromagnetically induced transparency (EIT), providing a direct nondestructive …

We review here the studies performed about interactions in an assembly of cold Rydberg
atoms. We focus especially on the review of the dipole–dipole interactions and on the effect …

By using a magneto-optical trap we have measured the Rb ns−(n+ 1) s and nd j−(n+ 1) dj
two-photon millimeter-wave transitions for 32<~ n<~ 3 7, observing 100-kHz-wide …

We analyze the effects of Zeeman degeneracies on the long-range interactions between like
Rydberg atoms, with particular emphasis on applications to quantum-information processing …

In cold dense Rydberg atom samples, the dipole-dipole interaction strength is effectively
resonant at the typical interatomic spacing in the sample, and the interaction has a 1/R 3 …

When an excited atomic electron interacts with a neutral perturbing atom or molecule that
possesses a shape resonance, it generates a characteristic class of Born-Oppenheimer …

We report optical absorption imaging of ultracold neutral strontium plasmas. The ion
absorption spectrum determined from the images is Doppler broadened and thus provides a …

We study experimentally the line of a single quantized vortex in a rotating prolate Bose-
Einstein condensate confined by a harmonic potential. In agreement with predictions, we …
