利用连续矩阵乘积态变分方法研究了一维${}^{6} Li $-${}^{40} K $吸引费米混合气体，得到了$T=0$相图.我们预测一个轴向密度分布，其中包含四个不同的相位捕获诱导沿沿着一维（1D）管，这是更复杂的比在1D质量平衡系统或在高维气体云中观察到的。探索的参数制度是现实的，鉴于未来可能的实验。这是连续矩阵乘积态在不可积费米子系统中的应用.
We study the attractive Fermi mixture of a ${}^{6}\mathrm{Li}$-${}^{40}\mathrm{K}$ gas in one dimension using the continuous matrix product states variational ansatz and obtain the $T=0$ phase diagram. We predict an axial density profile that contains four distinct phases trapped induced along one-dimensional (1D) tubes, which is more intricate than those observed in 1D mass-balanced systems or in higher-dimensional gas clouds. The parameter regimes explored are realistic in view of possible future experiments. This an application of continuous matrix product states to a nonintegrable fermionic system.
