论文摘要
提出了有关具有自限制的一二二二液液滴（6）$ \ times $ su（2）超低效率混合物的扩散蒙特卡洛计算。我们发现，即使仅具有两种旋转类型的有吸引力的相互作用的布置不是自我限制，但与至少三种费米子的混合物形成了稳定的小滴。但是，对于非常紧密的限制，稳定化降低了，在Fermi-Fermi和Fermi-Boson簇中发现了普遍的行为，包括有吸引力和排斥性的相互作用。
Diffusion Monte Carlo calculations on the possibility of having self-bound one-dimen\-sional droplets of SU(6) $\times$ SU(2) ultracold fermionic mixtures are presented. We found that, even though arrangements with attractive interactions with only two spin types are not self-bound, mixtures with at least three kinds of fermions form stable small drops. However, that stabilization decreases for very tight confinements, where a universal behavior is found for Fermi-Fermi and Fermi-Boson clusters including attractive and repulsive interactions.
