标题： Universal Turbulent States of Miscible Two-Component Bose-Einstein Condensates

摘要： 我们使用耦合的Gross-Pitaevskii方程研究受限于箱势中的可混溶两组分玻色-爱因斯坦凝聚体中的湍流。 湍流由振荡力驱动，导致各组分以同相（共振）或反相（反振）的方式振荡。 一个衡量组分分离程度的参数（重叠时为0，完全分离时为1）揭示了两种湍流状态：耦合（参数$\sim0$）和解耦（参数$\sim0.5$）。 共振流动在临界相互作用强度下在这两种状态之间转换，而反振流动始终表现出解耦状态。 一个概率模型预测解耦状态的参数为$\sqrt{4/\pi - 1} = 0.523$，与模拟结果一致。 显示英文摘要

摘要： We investigate turbulence in miscible two-component Bose-Einstein condensates confined in a box potential using the coupled Gross-Pitaevskii equations. Turbulence is driven by an oscillating force, causing the components to oscillate either in-phase (co-oscillating) or out-of-phase (counter-oscillating). A parameter measuring component separation (0 for overlap, 1 for full separation) reveals two turbulent states: coupled (the parameter $\sim0$) and decoupled (the parameter $\sim0.5$). Co-oscillating flows transition between these states at a critical interaction strength, while counter-oscillating flows consistently show the decoupled state. A probabilistic model predicts the decoupled state's parameter as $\sqrt{4/\pi - 1} = 0.523$, consistent with simulations.
