Coherent Backscattering of Ultracold Atoms [PDF]
Physical Review Letters, 2012 We report on the direct observation of coherent backscattering (CBS) of ultracold atoms, in a quasi-two-dimensional configuration. Launching atoms with a well-defined momentum in a laser speckle disordered potential, we follow the progressive build up of

Scattering Models for Ultracold Atoms [PDF]
Annals of Physics, 2008 We present a review of scattering models that can be used to describe the low-energy behavior of identical bosonic atoms. In the simplest models, the only degrees of freedom are atoms in the same spin state.

Exotic Chemistry with Ultracold Rydberg Atoms
CHIMIA, 2016 We review recent experiments carried out with dense (1012 cm–3) ultracold (T = 40 ?K) samples of Cs atoms which have the goal to characterize, by high-resolution spectroscopy, the interactions between Cs atoms, Cs+ ions and electrons that lead ...

Ultracold atom interferometry in space
Nature Communications, 2021 AbstractBose-Einstein condensates (BECs) in free fall constitute a promising source for space-borne interferometry. Indeed, BECs enjoy a slowly expanding wave function, display a large spatial coherence and can be engineered and probed by optical techniques.

Ultracold Atoms Out of Equilibrium [PDF]
Annual Review of Condensed Matter Physics, 2015 The relaxation of isolated quantum many-body systems is a major unsolved problem connecting statistical and quantum physics. Studying such relaxation processes remains a challenge despite considerable efforts. Experimentally, it requires the creation and manipulation of well-controlled and truly isolated quantum systems.

The manipulation of ultracold atoms of high orbitals in optical lattices
Frontiers in Physics, 2022 Ultracold atoms in optical lattices are a powerful tool for quantum simulation, precise measurement, and quantum computation. A fundamental problem in applying this quantum system is how to manipulate the higher bands or orbitals in Bloch states ...

Nanoplasmonic Lattices for Ultracold Atoms
Physical Review Letters, 2012 We propose to use sub-wavelength confinement of light associated with the near field of plasmonic systems to create nanoscale optical lattices for ultracold atoms. Our approach combines the unique coherence properties of isolated atoms with the sub-wavelength manipulation and strong light-matter interaction associated with nano-plasmonic systems.
