Width of the confinement-induced resonance in a quasi-one-dimensional trap with transverse anisotropy
We theoretically study the width of the s-wave confinement-induced resonance
(CIR) in quasi-one-dimensional atomic gases under tunable transversely
anisotropic confinement. We find that the width of the CIR can be tuned by
varying the transverse anisotropy. The change in the width of the CIR can
manifest itself in the position of the discontinuity in the interaction energy
density, which can be probed experimentally.Comment: 6 pages, 3 figures, update references, published versio
