论文摘要
我们调查了$^6 $ li原子的费米气体的三体重组率在Quasi-1d中被限制在$ p $ - 波菲斯巴赫共鸣附近。我们确认，准1D损耗率常数$ k_3 $遵循预测的阈值缩放定律，即$ k_3 $在共振上是独立的，并且与缩放定律$ k_3 \ propto（k \，a_ {1d}）^6 $远离共振[mehta等人[mehta等。物理。 Rev. A 76，022711（2007）]。此外，我们基于BREIT-WIGNER分析发展了一个理论，该理论描述了中间场的损失特征。最后，我们测量损耗率常数如何用横向限制来衡量尺度，并发现$ k_3 \ propto v_l^{ - 1} $，其中$ v_l $是晶格深度。重要的是，在我们可实现的横向限制和温度下，我们看到了在准1D中对现有的三体损耗率常数的74倍，而3D则是3D。随着横向限制的进一步增强，这种抑制可能为实现稳定的$ p $ - 波超流体铺平了道路。
We investigate the three-body recombination rate of a Fermi gas of $^6$Li atoms confined in quasi-1D near a $p$-wave Feshbach resonance. We confirm that the quasi-1D loss rate constant $K_3$ follows the predicted threshold scaling law that $K_3$ is energy independent on resonance, and find consistency with the scaling law $K_3 \propto (k \, a_{1D})^6$ far from resonance [Mehta et al. Phys. Rev. A 76, 022711 (2007)]. Further we develop a theory based on Breit-Wigner analysis that describes the loss feature for intermediate fields. Lastly we measure how the loss rate constant scales with transverse confinement and find that $K_3 \propto V_L^{-1}$, where $V_L$ is the lattice depth. Importantly, at our attainable transverse confinements and temperatures, we see a 74-fold suppression of the on-resonant three-body loss rate constant in quasi-1D compared to 3D. With significant further enhancement of the transverse confinement, this suppression may pave the way for realizing stable $p$-wave superfluids.
