Abstract
We discuss stability and phase coherence of 1D trapped Bose gases and find that inelastic decay processes, such as three-body recombination, are suppressed in the strongly interacting (Tonks-Girardeau) and intermediate regimes. This is promising for achieving these regimes with a large number of particles. ”Fermionization” of the system reduces the phase coherence length, and at the gas is fully phase coherent only deeply in the weakly interacting (Gross-Pitaevskii) regime.
