摘要:

我们研究了具有关联对角无序的一维紧束缚晶格中反常量子波函数振幅的爆发。这种类似流氓浪潮的行为是由本地化和移动性之间的竞争所促成的。无序的有效相关长度最终负责使局部无序强度达到最小值,从而促进更高振幅的极端事件的发生,特别是与不相关无序的情况相比时。我们的研究结果是有效的一类离散的一维系统,揭示了深刻的方面的作用,随机性在流氓波的产生。

英文摘要:

We investigate the outbreak of anomalous quantum wavefunction amplitudes in a one-dimensional tight-binding lattice featuring correlated diagonal disorder. Such rogue-wave-like behavior is fostered by a competition between localization and mobility. The effective correlation length of the disorder is ultimately responsible for bringing the local disorder strength to a minimum, fuelling the occurrence of extreme events of much higher amplitudes, specially when compared to the case of uncorrelated disorder. Our findings are valid for a class of discrete one-dimensional systems and reveal profound aspects of the role of randomness in rogue-wave generation.
