论文摘要
给出了针对均匀和捕获系统的两组分统一气体和人口不平衡的两组分统一气体的相图的详细描述。这旨在为温度极化参数空间中的质量失去平衡的费米气体的正常流体流体过渡提供定量基准。采用了一种自洽的T-Matrix方法，该方法已被证明可以准确描述质量和人口的热力学特性平衡的单一费米气体。我们的结果为杂核费米混合物的持续实验提供了指南。
A detailed description is given of the phase diagram for a two-component unitary Fermi gas with mass and population imbalance, for both homogeneous and trapped systems. This aims at providing quantitative benchmarks for the normal-to-superfluid phase transition of a mass-imbalanced Fermi gas in the temperature-polarization parameter space. A self-consistent t-matrix approach is adopted, which has already proven to accurately describe the thermodynamic properties of the mass and population balanced unitary Fermi gas. Our results provide a guideline for the ongoing experiments on heteronuclear Fermi mixtures.
