Crystallography of optical lattices
Physical Review A, 1994We present a theoretical study of three- and four-beam configurations that generalize, in the two-dimensional (2D) and three-dimensional (3D) cases, the well-known 1D lin \ensuremath{\perp} lin (two counterpropagating beams having crossed linear polarizations) and magnetic-assisted Sisyphus effect cooling schemes. It is shown how the Bravais lattice is

Engineering novel optical lattices
Reports on Progress in Physics, 2013Optical lattices have developed into a widely used and highly recognized tool to study many-body quantum physics with special relevance for solid state type systems. One of the most prominent reasons for this success is the high degree of tunability in the experimental setups.

The precision measurement of time and frequency is a prerequisite not only for fundamental science but also for technologies that support broadband communication networks and navigation with global positioning systems (GPS). The SI second is currently realized by the microwave transition of Cs atoms with a fractional uncertainty of 10(-15) (ref.

We report on the precision spectroscopy of the 5s/sup 2/ /sup 1/S/sub o/(F=9/2)-5s5p /sup 3/P/sub o/(F=9/2) clock transition of /sup 87/Sr atoms trapped in a one-dimensional optical lattice and discuss its prospects as a future optical clock.

Optics Letters, 1996
We study a new type of optical lattice in which the localized atoms experience a much reduced optical pumping and fluorescence rate. An optical standing wave is tuned to the blue of the F = 2 ? F = 2 transition of the (87)Rb D(2) line and induces periodic optical potentials by coupling the F = 2 ground state to both the F = 2 and F = 3 excited states ...

A new breed of atomic clock—the “ticking” of which comes from transitions in millions of cooled atoms, trapped in optical standing waves created by tightly focused lasers—is pushing scientific timekeeping to previously unknown frontiers of precision.

Quasiperiodic Optical Lattices
Physical Review Letters, 1997We study the kinetic temperature and the localization of cesium atoms in a three dimensional quasiperiodic optical potential created by the interference of five or six laser beams. Bragg scattering experiments show evidence of a quasiperiodic order for the atomic density.

We have spatially resolved ~250 single, neutral atoms in a 3D array. The atoms are trapped in a blue-detuned optical lattice, and can function as qubits in a quantum computer. Article not available.

Physical Review A, 2004
We propose a scheme that allows us to Fourier-synthesize arbitrarily shaped periodic potentials for atoms. The method is based on the dispersion connected with higher order multiphoton Raman processes, where a suitable combination of laser frequencies eliminates unwanted standing wave effects.
