论文摘要
我们研究了$ p $ - 波（$ p $ wave feshbach resonance in Ultracold $^6 $ li atoms）的碰撞损失。我们测量了$ p $ - 波的共振在准1D中的位置，并观察到限制引起的变化和拓宽。我们发现，三体损失系数$ L_3 $作为准1D限制的功能几乎不依赖于监禁强度。我们还使用两步级联的三体损失模型分析了原子损失，在该模型中，在原子二聚体碰撞引起的损失之前，形成弱结合的二聚体。我们的数据与此模型一致。我们还发现具有强大的准1D限制的二聚体松弛速率可能抑制。我们讨论了这些测量值对观察$ p $ - 波的配对的含义。
We study collisional loss of a quasi-one-dimensional (1D) spin-polarized Fermi gas near a $p$-wave Feshbach resonance in ultracold $^6$Li atoms. We measure the location of the $p$-wave resonance in quasi-1D and observe a confinement-induced shift and broadening. We find that the three-body loss coefficient $L_3$ as a function of the quasi-1D confinement has little dependence on confinement strength. We also analyze the atom loss with a two-step cascade three-body loss model in which weakly bound dimers are formed prior to their loss arising from atom-dimer collisions. Our data are consistent with this model. We also find a possible suppression in the rate of dimer relaxation with strong quasi-1D confinement. We discuss the implications of these measurements for observing $p$-wave pairing in quasi-1D.
