极性凝聚体的费米稳定化和密度波基态
Fermionic stabilization and density-wave ground state of a polar condensate
摘要：
我们研究了在T=0时被困偶极凝聚体与单组分费米子气体混合的稳定性。而纯偶极凝聚与小的s波相互作用是不稳定的，即使小偶极-偶极相互作用强度，我们发现，费米子的混合物可以显着稳定它们，这取决于玻色子-费米子相互作用的强度。在稳定的制度，我们发现一个区域的基态的特点是沿软陷阱方向的密度波。
英文摘要：
We examine the stability of a trapped dipolar condensate mixed with a single-component fermion gas at T=0. Whereas pure dipolar condensates with small s-wave interaction are unstable even for small dipole-dipole interaction strength, we find that the admixture of fermions can significantly stabilize them, depending on the strength of the boson-fermion interaction. Within the stable regime we find a region where a ground state is characterized by a density wave along the soft trap direction.
