Phys. Rev. Lett. 90, 010401 (2003) [4 pages]Stability and Phase Coherence of Trapped 1D Bose GasesReceived 24 July 2002; published 2 January 2003 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 T=0 the gas is fully phase coherent only deeply in the weakly interacting (Gross-Pitaevskii) regime. © 2003 The American Physical Society URL:
