论文摘要
我们讨论由玻色子和自旋偏振的费米原子组成的混合物的平均平均场特性，其在任意尺寸$ 2 <d <4 $中的点状相互作用。特别是，我们讨论了系统的标准弱偶联极限，其略有耗尽的玻色冷凝物和几乎理想的费米气体（元）稳定相位，其二聚体恰好由一个玻色子和一个费米亚组成。阐明了费米 - 二聚体和玻色子二聚体三体有效相互作用的特殊性及其对稀玻色纤维纤维混合物的热力学稳定性的影响。
We discuss an equilibrium mean-field properties of mixtures consisting of bosons and spin-polarized fermionic atoms with a point-like interaction in an arbitrary dimension $2<d<4$. Particularly, we discuss except the standard weak-coupling limit of the system with slightly depleted Bose condensate and almost ideal Fermi gas, the (meta)stable phase with dimers composed exactly of one boson and one fermion. The peculiarities of the fermion-dimer and the boson-dimer three-body effective interactions and their impact on the thermodynamic stability of the dilute Bose-Fermi mixtures are elucidated.
