超冷气体领域的最新进展已经允许创建相分离的玻色-费米系统。我们提出了一个理论研究的集体激发在零温度。随着费米子到玻色子粒子数的增加，集体模式频率的值介于完全玻色子云和完全费米子云之间，中间区域有阻尼。这种阻尼是由界面处共振驱动的费米子引起的。
Recent progress in the field of ultracold gases has allowed for the creation of phase-segregated Bose-Fermi systems. We present a theoretical study of their collective excitations at zero temperature. As the fraction of fermion-to-boson particle number increases, the collective mode frequencies take values between those for a fully bosonic and those for a fully fermionic cloud, with damping in the intermediate region. This damping is caused by fermions which are resonantly driven at the interface.
