论文摘要

我们通过类比与Bose-Einstein凝结到Bardeen-cooper--schrieffer-schrieffer crossover在两个组成的费米子系统中,我们讨论了强Quark跨界的库克三元组(库珀对的三体对应物)。这样的交叉与相位过渡不同,后者通常涉及对称性破坏。我们从三体$ t $ matrix中计算出中型三体能量,其现象学三体力是表征真空中绑定的雄激素状态的三体力。随着密度的增加,HADRONIC BOND-StATE POL平滑地经历了cooper三相的交叉,其中三体内部三体簇与夸克·费米·海(Quark Fermi Sea)共存。与Quarkyonic物质模型的关系也可以自然地找到。

We discuss the hadron--quark crossover accompanied by the formation of Cooper triples (three-body counterpart of Cooper pairs) by analogy with the Bose--Einstein condensate to Bardeen--Cooper--Schrieffer crossover in two-component fermionic systems. Such a crossover is different from a phase transition, which often involves symmetry breaking. We calculate the in-medium three-body energy from the three-body $T$-matrix with a phenomenological three-body force characterizing a bound hadronic state in vacuum. With increasing density, the hadronic bound-state pole smoothly undergoes a crossover toward the Cooper triple phase where the in-medium three-body clusters coexist with the quark Fermi sea. The relation to the quarkyonic matter model can also be found in a natural manner.
