All common decoherence and atom loss mechanisms are shown to be small. We discuss general consequences of a non-parabolic confinement potential, in particular novel two-body shape resonances, which could be observed in this trap.4 pages, submittedOther Condensed MatterQuantum PhysicsShape resonances for ultracold atom gases in carbon nanotube waveguidestext
