论文摘要

弱相互作用的费米气体模拟了能量空间中的自旋晶格,提供了一个丰富的平台,用于调查大型多体量子系统中的信息传播和自旋连贯性。我们表明,可以从测得的旋转密度中确定集体自旋载体作为能量的函数,从而实现了一般的能空解决方案。我们测量该系统中的超阶相关函数,并观察多体相干性的能量依赖性。

Weakly interacting Fermi gases simulate spin-lattices in energy-space, offering a rich platform for investigating information spreading and spin coherence in a large many-body quantum system. We show that the collective spin vector can be determined as a function of energy from the measured spin density, enabling general energy-space resolved protocols. We measure an out-of-time-order correlation function in this system and observe the energy dependence of the many-body coherence.
