论文摘要
通过使用简单有效的方法，我们讨论了浸入三维bose气体中的单个杂质的特性，并与调谐到单一极限的颗粒之间的相互作用。特别是，采用平均场状近似值，我们介绍了杂质谱的低摩肌参数的首次估计，即结合能，有效的质量和准粒子残基，均用于单位气体中的排斥和有吸引力的玻色极性。
By using simple and efficient method we discuss properties of a single impurity immersed in three-dimensional Bose gas with the interaction between particles tuned to unitary limit. Particularly, adopting the mean-field-like approximation we present the first estimations for the low-momentum parameters of the impurity spectrum, namely, the binding energy, the effective mass and the quasiparticle residue both for repulsive and attractive Bose polarons in the unitary gas.
