Atomic Bose and Anderson Glasses in Optical Lattices

Atomic Bose and Anderson glasses in optical lattices.

An ultracold atomic Bose gas in an optical lattice is shown to provide an ideal system for the controlled analysis of disordered Bose lattice gases. This goal may be easily achieved under the current experimental conditions by introducing a pseudorandom potential created by a second additional lattice or, alternatively, by placing a speckle pattern on the main lattice. We show that, for a nonco...

Routes towards Anderson-like localization of Bose-Einstein condensates in disordered optical lattices.

We investigate, both experimentally and theoretically, possible routes towards Anderson-like localization of Bose-Einstein condensates in disordered potentials. The dependence of this quantum interference effect on the nonlinear interactions and the shape of the disorder potential is investigated. Experiments with an optical lattice and a superimposed disordered potential reveal the lack of And...

Bose-Einstein condensation in optical lattices

The advent of coherent matter waves in the form of Bose-Einstein condensation, coupled with periodic potentials in the form of optical lattices, has established a new area of research on the boundary between atomic and condensed matter physics. This essay is a brief review of the recent theoretical and experimental progress in the area of degenerate Bose gases loaded into optical lattices. PDF ...

Bose-Einstein Condensates in Optical Quasicrystal Lattices

Producing Bose-Einstein condensates using optical lattices.

We relate the entropies of ensembles of atoms in optical lattices to atoms in simple traps. We then determine which ensembles of lattice-bound atoms will adiabatically transform into a Bose condensate. This shows a feasible approach to Bose condensation without evaporative cooling.
