论文摘要
当气体对塌陷的平均场趋势稳定在平均场外波动以外的有效排斥力稳定时，会形成自绑的量子液滴。超出平均场效应取决于狂犬病$ω_r$和二次zeeman效应$ q $，分别为狂犬耦合的玻色混合物和旋转气体。最近已经检查了零变化的Rabi Coupled Bose混合物，而零不谐振$δ= 0 $以及$ \ langle f_z \ langle f_z \ rangle = 0 $，对$ω_r$和$ q $的影响对量子液滴的影响最近进行了检查。在本文中，我们从理论上探讨了液滴相对于极化$δ\ neq 0 $ rabi耦合的玻色混合物和$ \ langle f_z \ rangle \ neq 0 $ spinor Gas的稳定性。我们计算了带有偏光订单参数的两种气体的Lee-huang-yang校正，并在$ω_r$ - $δ$和$ q $Δ$和$ Q $ -P $的参数空间上获得液滴的相图，用于Rabi Coupled混合物和旋转器气体。最后，我们强调了两个系统之间的相似性和差异，并讨论了它们的实验性可行性。
Self-bound quantum droplets form when the mean-field tendency of the gas to collapse is stabilized by the effectively repulsive beyond mean-field fluctuations. The beyond mean-field effects depend on Rabi-frequency $ω_R$ and quadratic Zeeman effect $q$ for the Rabi-coupled Bose mixtures and the spinor gases, respectively. The effects of varying $ω_R$ and $q$ on the quantum droplet have recently been examined for unpolarized Rabi-coupled Bose mixture with zero detuning $δ= 0$ and unpolarized spinor gas with $\langle F_z \rangle=0$. In this paper, we theoretically explore the stability of the droplet phase for polarized $δ\neq 0$ Rabi-coupled Bose mixture and $\langle F_z \rangle \neq 0$ spinor gas. We calculate the Lee-Huang-Yang corrections for both gases with polarized order parameters and obtain the phase diagram of the droplets on the parameter space of $ω_R$-$δ$ and $q$-$p$ for Rabi-coupled mixture and spinor gas, respectively. Finally, we highlight the similarities and differences between the two systems and discuss their experimental feasibility.
