论文摘要
我们描述了由外部谐波力沿一个空间方向挤压的玻璃豆混合物的量子液滴。我们的方法基于[1]中提出的自洽方法。在限制方向上的真实空间液滴轮廓是为了，但是在自由方向上假设局部密度近似。我们定义了一种数值方法，可以找到对化学势（Lee-huang-yang化学势）的超越场贡献 - 决定了液滴剖面的数量。除了数值方法外，我们还发现了两种限制情况下的分析形式中的Lee-huang-yang潜力：当限制非常弱时，强烈限制的扰动结果和半经典表达。
We describe a quantum droplet of a Bose-Bose mixture squeezed by an external harmonic forces in one spatial direction. Our approach is based on the self-consistent method formulated in [1]. The true spatial droplet profile in the direction of confinement is accounted for, however local density approximation is assumed in the free directions. We define a numerical approach to find the beyond-mean-field contribution to the chemical potential (Lee-Huang-Yang chemical potential) -- the quantity that determines the droplet's profile. In addition to the numerical approach, we find the Lee-Huang-Yang potential in the analytic form in two limiting cases: a perturbative result for a strong confinement and a semiclassical expression when confinement is very weak.
