We present phase diagrams for population-imbalanced, trapped Fermi superfluids near unitarity. In addition to providing quantitative values for the superfluid transition temperature, the pairing onset temperature, and the transition line (separating the Sarma and phase separation regimes), we study experimental signatures of these transitions based on density profiles and density differences at the center. Predictions on the BCS side of resonance show unexpected behavior, which should be searched for experimentally.
我们给出了接近幺正性的粒子数失衡、捕获费米超流体的相图。除了给出超流转变温度、配对起始温度以及转变线(分隔萨马相和相分离区域)的定量值外,我们还基于密度分布和中心处的密度差研究了这些转变的实验特征。共振的BCS一侧的预测显示出意想不到的行为,这应该通过实验来寻找。
