论文摘要
我们研究了半体体 - efimov效应，该效应是针对各种系统中具有共鸣三体相互作用的四个相同的玻色子。基于结合状态和重归化组方程的解决方案，我们首先证明了2D中半体体 - efimov效应的出现。与Efimov和超级效果相比，即使在极度质量失去平衡的情况下，质量比率依赖性比例缩放参数也会出现有限的值，而质量比为0或$ \ yfty $。通过重新归一化组的分析，我们还表明，弱的两体相互作用维持了半生体效应。最后，我们通过表明具有线性分散关系的玻色子支持1D的半usper-efimov效应，从而使半卵效应的效应从2D解放了普遍性。
We study the semisuper-Efimov effect, which is found for four identical bosons with a resonant three-body interaction in 2D, in various systems. Based on solutions of bound-state and renormalization-group equations, we first demonstrate an emergence of the semisuper-Efimov effect in mass-imbalanced bosons in 2D. Compared with the Efimov and the super-Efimov effects, the mass ratio-dependent scaling parameter is unexpectedly found to take on a finite value even for extremely mass-imbalanced situations, where the mass ratio is 0 or $\infty$. By a renormalization-group analysis, we also show that a weak two-body interaction sustains the semisuper-Efimov effect. Finally, we liberate the universality of the semisuper-Efimov effect from 2D by showing that bosons with linear-dispersion relation support the semisuper-Efimov effect in 1D.
