论文摘要
我们研究了三个相同玻色子的Efimov物理学，具有成对的多通道相互作用，以进行可调宽度的Feshbach共振。我们发现，相互作用的两体多通道性质会影响通用的三体频谱，尤其是对于中间宽度的共振。这种通用频谱中的变化是由将封闭的相互作用通道中的三聚体状态引起的，这些通道将其与通用埃菲莫夫态相对。但是，在狭窄的共振极限中，我们发现Efimov频谱是由共振宽度参数$ r^*$仅与所考虑的相互作用势相关的。在广泛的共振限制中，所有激发的Efimov Trimer Energies都将相应的单渠道系统中的能量用于所研究的情况。
We study Efimov physics of three identical bosons with pairwise multichannel interactions for Feshbach resonances of adjustable width. We find that the two-body multichannel nature of the interaction can affect the universal three-body spectrum, especially for resonances of intermediate width. The shifts in this universal spectrum are caused by trimer states in the closed interaction channels that couple to the universal Efimov states. However, in the narrow resonance limit we find that the Efimov spectrum is set by the resonance width parameter $r^*$ only independent of the interaction potential considered. In the broad resonance limit all excited Efimov trimer energies approach the ones from the corresponding single-channel system for the scenarios investigated.
