EXPERIMENTAL STUDY OF A BOSE GAS IN ONE DIMENSION

摘要

There has recently been considerable interest in reduced-dimensionality systems involving trapped Bose gases. For example, a gas that would be weakly interacting in 3D can be strongly correlated in 1D permitting the study of phenomena beyond mean field theory. Understanding the coherence properties of 1D systems may be important for atom interferometers using atomic waveguides. This short, qualitative paper provides an extended abstract of our presentation at ICOLS 03 which described our recent studies of 1D Bose gases. Here we report on both the observation of a strong reduction in the three-body recombination rate in 1D gases due to their correlation properties, and the observation of a 1D Mott transition when these 1D gases are loaded into a 1D optical lattice.
