论文摘要
我们从实验和理论上研究了两组分的费米凝结物在强烈相互作用的方向上对相互作用强度淬灭的反应。使用射频$π$ -Pulse到具有不同的相互作用强度的第三个内部水平来实现淬火。我们发现，淬灭在流体动力学方面激发了陷阱的单极模式，并且冷凝物特性的初始变化是在时间尺度上进行的，甚至比准粒子弛豫时间比较大。
We study experimentally and theoretically the response of a two-component Fermi condensate in the strongly-interacting regime to a quench of the interaction strength. The quench is realized using a radio-frequency $π$-pulse to a third internal level with a different interaction strength. We find that the quench excites the monopole mode of the trap in the hydrodynamic regime and that an initial change of the condensate properties takes place on a time scale comparable or even larger than the quasi-particle relaxation time.
