Multichannel Effects near Confinement-Induced Resonances in Harmonic Waveguides
arXiv:1107.2501 · doi:10.1103/PhysRevA.84.042712
Abstract
We analyze the impact of multichannel scattering in harmonic waveguides on the positions and widths of confinement-induced resonances for both isotropic and anisotropic transversal confinement. Multichannel scattering amplitudes and transmission coefficients are calculated and used to characterize the resonant behaviour of atomic collisions with varying anisotropy. A mechanism is established which leads to a splitting of the confinement-induced resonance in the presence of anisotropy.
