High-efficiency cold-atom transport into a waveguide trap

Bose-stimulated scattering off a cold atom trap

The angle and temperature dependence of the photon scattering rate for Bose-stimulated atom recoil transitions between occupied states is compared to diffraction and incoherent Rayleigh scattering near the Bose-Einstein transition for an optically thin trap in the limit of large particle number, N . Each of these three processes has a range of angles and temperatures for which it dominates over...

Constructing a Magneto-optical Trap for Cold Atom Trapping

High-density mesoscopic atom clouds in a holographic atom trap

We demonstrate the production of micron-sized high-density atom clouds of interest for mesoscopic quantum information processing. We evaporate atoms from 60 !K, 3"1014 atoms/cm3 samples contained in a highly anisotropic optical lattice formed by interfering diffracted beams from a holographic phase plate. After evaporating to 1 !K by lowering the confining potential, in less than a second the a...

Experimental measurement of efficiency and transport coherence of a cold-atom Brownian motor in optical lattices.

The rectification of noise into directed movement or useful energy is utilized by many different systems. The peculiar nature of the energy source and conceptual differences between such Brownian motor systems makes a characterization of the performance far from straightforward. In this work, where the Brownian motor consists of atoms interacting with dissipative optical lattices, we adopt exis...
