| The momentum pair distributions for the four different regions of potential imbalance γ = 4 in Fig. 1 . The attractive interactions are (a) u = −1.6 for the FP-FFLO2 phase, (b) u = −2.0 for the FP-FFLO1 phase, (c) u = −2.4 for the polarized normal phase, and (d) u = −3.0 for the BCS phase. The inset magnifies the region around the peak. |
