我们研究了40K和87Rb原子的费米-玻色混合物中耦合偶极振荡的动力学。这种低能量集体模式受到种间相互作用的强烈影响。测量在经典和量子简并状态下进行，揭示了混合物的统计特性的关键作用。在量子简并开始时，我们分别研究了泡利阻塞和超流动性对K原子和Rb原子的作用，它们导致碰撞相互作用的变化。
We study the dynamics of coupled dipolar oscillations in a Fermi–Bose mixture of 40K and 87Rb atoms. This low-energy collective mode is strongly affected by the interspecies interactions. Measurements are performed in the classical and quantum degenerate regimes and reveal the crucial role of the statistical properties of the mixture. At the onset of quantum degeneracy, we investigate the role of Pauli blocking and superfluidity for K and Rb atoms, respectively, resulting in a change in the collisional interactions.
