一种异质双组分玻色混合物中的杂质

An impurity in a heteronuclear two-component Bose mixture

Giacomo Bighin, Alessia Burchianti, Francesco Minardi, Tommaso Macrì

摘要:

我们研究了杂质在超冷异质玻色混合物中的命运,重点是实验相关的$^{41}$ $^{87}$ Rb混合物的情况,杂质处于$^{41}$ K超精细态。我们的工作提供了一个全面的描述BEC混合物中的杂质与接触的相互作用,其相图。我们目前的结果为混溶和不混溶的制度,以及在一个自约束量子液滴的杂质。在这里,不同的相互作用,我们发现新的,异国情调的状态,杂质本地化的中心或表面的液滴。

英文摘要:

We study the fate of an impurity in an ultracold heteronuclear Bose mixture, focusing on the experimentally relevant case of a $^{41}$K-$^{87}$Rb mixture, with the impurity in a $^{41}$K hyperfine state. Our work provides a comprehensive description of an impurity in a BEC mixture with contact interactions across its phase diagram. We present results for the miscible and immiscible regimes, as well as for the impurity in a self-bound quantum droplet. Here, varying the interactions, we find novel, exotic states where the impurity localizes either at the center or at the surface of the droplet.
