Sideband cooling of neutral atoms in a far-detuned optical lattice
TLDR
In this paper, sideband laser cooling using stimulated Raman transitions is performed on trapped cesium atoms, where the confinement is produced by a far off-resonance dipole trap consisting of two crossed YAG beams which, by interference, create a one-dimensional optical lattice.Abstract:
Sideband laser cooling using stimulated Raman transitions is performed on trapped cesium atoms. The confinement is produced by a far–off-resonance dipole trap consisting of two crossed YAG beams which, by interference, create a one-dimensional optical lattice. In a pure intensity lattice, we measure a 1D temperature of T = 6 μK corresponding to a mean quantum vibrational number of about nv = 0.75. In a polarization gradient lattice, the final temperature is T = 3.6 μK corresponding to nv 2.4.read more

Optical Dipole Traps for Neutral Atoms
TL;DR: In this article, optical dipole traps for neutral atoms have been used for storage and trapping of charged and neutral atoms in the vast energy range from elementary particles to ultracold atomic quantum matter.

Quantum information processing with atoms and photons
TL;DR: Recent theoretical and experimental advances suggest that cold atoms and individual photons may lead the way towards bigger and better quantum information processors, effectively building mesoscopic versions of 'Schrödinger's cat' from the bottom up.

Bose-Einstein Condensation of Cesium
TL;DR: Various regimes of condensate self-interaction (attractive, repulsive, and null interaction strength) are explored and properties of imploding, exploding, and non-interacting quantum matter are demonstrated.

Cooling a single atom in an optical tweezer to its quantum ground state
TL;DR: In this paper, a single neutral atom is cooled to its vibrational ground state in an optical tweezer, and the spin and motional states of the trapped atom are observed via sideband spectroscopy.

Laser Cooling to the Zero-Point Energy of Motion
TL;DR: A single trapped 198 Hg + ion was cooled by scattering laser radiation that was tuned to the resolved lower motional sideband of the narrow 2 S 1/2 - 2 D 5/2 transition to indicate that the ion was in the ground state of its confining well approximately 95% of the time.

Adiabatic cooling of cesium to 700 nK in an optical lattice.
TL;DR: This work localizes Cs atoms in wavelength-sized potential wells of an optical lattice, and cool them to athree-dimensional temperature of 700 nK by adiabatic expansion, causing the atomiccenter-of-mass distribution to expand and the temperature to decrease by an amount which agrees with simple 3D band theory.

Collective laser cooling of trapped atoms
TL;DR: In this paper, it was shown that by a sufficiently slow repumping process, one can avoid the problems of reabsorptions in laser cooling of trapped atoms, even in the case of optically thick samples.
