论文摘要
我们揭示了跨Bose-Hubbard模型的动态状态的多体干扰的签名。增加颗粒的不可区分性可以增强几种观察力的时间波动,并在量子混乱开始时具有巨大的扩增。通过解决部分可区分的粒子的交换对称性,我们将这种扩增解释为特征性特征性状态连贯性的指纹。
We unveil the signature of many-body interference across dynamical regimes of the Bose-Hubbard model. Increasing the particles' indistinguishability enhances the temporal fluctuations of few-body observables, with a dramatic amplification at the onset of quantum chaos. By resolving the exchange symmetries of partially distinguishable particles, we explain this amplification as the fingerprint of the initial state's coherences in the eigenbasis.
