Multiple-Channel Scattering Resonance of One-Dimensional Ultracold Spinor Bosons
arXiv:1401.5131 · doi:10.1103/PhysRevA.90.022705
Abstract
So far the interaction of ultacold atoms can only be tuned within one particular scattering channel near a resonance, where the spinor structure of atomic isotopes is destroyed due to the typically large magnetic field. In this Letter, we propose a scheme to realize {\it multiple-channel scattering resonance} (MCSR) of ultracold bosons in one-dimension while still keeping their spinor structure. The MCSR refers to a simultaneous scattering resonance among all different scattering channels, including those breaking SU(2) and SO(2) spin rotation symmetries. Essential ingredients for MCSR include the 3D interactions, the confinement potential and a spin-flipping field. Near MCSR a many-body spinor system exhibits exotic spin density distributions and pair correlations, which are significantly different from those near a single-channel resonance.
