摘要:

我们从实验和理论上研究了强相互作用区域中两组分费米凝聚体对相互作用强度猝灭的响应。使用射频$π$ -脉冲以不同的相互作用强度将猝灭实现到第三内部水平。我们发现,淬火激发的陷阱在流体动力学制度和冷凝物性质的初始变化发生在一个时间尺度上可比,甚至大于准粒子弛豫时间的模式。

英文摘要:

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.
