For this purpose, we prove bounds on both the eigenvalues and corresponding eigenfunctions of three-dimensional bosons in strongly elongated traps and relate them to the corresponding quantities in the Lieb-Liniger model. In particular, if both the scattering length a and the radius r of the cylindrical trap go to zero, the Lieb-Liniger model with coupling constant g ∼ a/r 2 is derived. Our bounds are uniform in g in the whole parameter range 0 ≤ g ≤ ∞, and apply to the Hamiltonian for three-dimensional bosons in a spectral window of size ∼ r -2 above the ground state energy.","lang":"eng"}],"extern":1,"quality_controlled":0,"date_updated":"2021-01-12T06:57:08Z","date_created":"2018-12-11T11:57:21Z","issue":"2","date_published":"2008-12-01T00:00:00Z","oa":1,"publication":"Communications in Mathematical Physics","year":"2008","main_file_link":[{"open_access":"1","url":"http://arxiv.org/abs/0709.4022"}],"volume":284,"citation":{"short":"R.
