我们研究了零温度下球对称谐波陷阱中双组分偶极费米气体的基态。在Thomas-Fermi-von Weizsacker近似的基础上，我们得到了磁矩值相等但相反的系统的相图。我们发现出现了一种相分离态，它自发地打破了系统的球对称性。
We study the ground state of a two-component dipolar Fermi gas in a spherically symmetric harmonic trap at zero temperature. On the basis of the Thomas–Fermi–von Weizsacker approximation, we obtain a phase diagram of the system with equal but opposite values of the magnetic moment. We find that a phase-separated state, which spontaneously breaks the spherical symmetry of the system, emerges.
