一维$SU(3)$费米子中具有三体相互作用的双极化子

Bipolaron in one-dimensional $SU(3)$ fermions with three-body interaction

O. Hryhorchak, G. Panochko, V. Pastukhov

AI总结:

本文研究一维$SU(3)$种群不平衡费米子在二体共振下的性质,考虑短程三体相互作用,发现三聚体和介质诱导二聚体态,并展示颜色超流证据。

摘要:

本文讨论了一维$SU(3)$种群不平衡费米子的性质。系统被假定处于二体共振状态,此时所有二体散射长度发散,费米子之间唯一考虑到的相互作用是短程三体相互作用。特别地,我们考虑仅有一种‘味’的费米子被宏观占据,而另外两种味各有两个原子的情形。该系统支持三聚体态和介质诱导的二聚体态,本文对此进行了详细研究,并展示了颜色超流的证据。

英文摘要:

The properties of the one-dimensional $SU(3)$ population-imbalanced fermions are discussed. The system is assumed to be in the two-body resonance where all two-body scattering lengths diverge, and the only interaction between fermions that is taken into account is the short-range three-body one. In particular, we consider the situation when only one `flavor' of fermions is macroscopically occupied, and there are exactly two atoms of two others. This system supports the trimer and the medium-induced dimer states studied here in detail and shows evidence of color superfluidity.
