通过数值求解零温下的Gross-Pitaevskii方程，从理论上研究了二元玻色-爱因斯坦凝聚相分离体系中畴尺寸的分布。我们表明，在域图案所产生的动态不稳定性的大小分布服从幂律的标度制度根据动态标度分析的基础上的逾渗理论。在弛豫动力学过程中保持缩放行为，直到特征域尺寸变得与系统的线性尺寸相当，与相序动力学的动态缩放假设一致。我们的数值实验表明，存在不同的标度制度的尺寸分布函数，这可能是由所谓的无芯涡。
Domain size distribution in phase separating binary Bose–Einstein condensates is studied theoretically by numerically solving the Gross–Pitaevskii equations at zero temperature. We show that the size distribution in the domain patterns arising from the dynamic instability obeys a power law in a scaling regime according to the dynamic scaling analysis based on the percolation theory. The scaling behavior is kept during the relaxation dynamics until the characteristic domain size becomes comparable to the linear size of the system, consistent with the dynamic scaling hypothesis of the phase-ordering kinetics. Our numerical experiments indicate the existence of a different scaling regime in the size distribution function, which can be caused by the so-called coreless vortices.
