摘要

我们演示了光学晶格中超冷原子的初始状态如何控制遍历动力学的出现，因为底层光谱结构被调谐到量子混沌状态。与相互作用强度相比，在隧道效应方面确定了不同初始状态的混沌阈值，以及混沌过渡的动态特征，在实验可观察到的水平和时间尺度上。

How to seed ergodic dynamics of interacting bosons under conditions of many-body quantum chaos

We demonstrate how the initial state of ultracold atoms in an optical lattice controls the emergence of ergodic dynamics as the underlying spectral structure is tuned into the quantum chaotic regime. Distinct initial states’ chaos threshold values in terms of tunneling as compared to interaction strength are identified, as well as dynamical signatures of the chaos transition, on the level of experimentally accessible observables and time scales.

期刊介绍： Reports on Progress in Physics is a highly selective journal with a mission to publish ground-breaking new research and authoritative invited reviews of the highest quality and significance across all areas of physics and related areas. Articles must be essential reading for specialists, and likely to be of broader multidisciplinary interest with the expectation for long-term scientific impact and influence on the current state and/or future direction of a field.
