论文摘要
我们使用动力学理论来模拟小岩石浓缩的重颗粒的云层的动力学。随着玻色纤维相互作用的改变,我们发现了整体和表面主导的状态之间的交叉 - 散射发生在整个玻色云中,或者仅在表面上。我们计算谐波陷阱中偶极模式的阻尼和频移,这是控制种间feshbach共振的磁场的函数。我们发现我们的随机模型与CS-LI混合物的实验研究之间有着极好的一致性。
We use kinetic theory to model the dynamics of a small Bose condensed cloud of heavy particles moving through a larger degenerate Fermi gas of light particles. Varying the Bose-Fermi interaction, we find a crossover between bulk and surface dominated regimes -- where scattering occurs throughout the Bose cloud, or solely on the surface. We calculate the damping and frequency shift of the dipole mode in a harmonic trap as a function of the magnetic field controlling an inter-species Feshbach resonance. We find excellent agreement between our stochastic model and the experimental studies of Cs-Li mixtures.
