We show that two intriguing features of mesoscopic transport, namely, the modulation of Coulomb blockade peak heights and the transmission phase lapses occurring between subsequent peaks, are closely related. Our analytic arguments are corroborated by numerical simulations for chaotic ballistic quantum dots. The correlations between the two properties are experimentally testable. The statistical distribution of the partial-width amplitude, at the heart of the previous relationship, is determined, and its characteristic parameters are estimated from simple models.
我们表明，介观输运中的两个有趣特征，即库仑阻塞峰高度的调制和随后的峰之间发生的传输相位滞后，密切相关。我们的分析论证得到了混沌弹道量子点的数值模拟的支持。这两种性质之间的相关性可以通过实验来检验。确定了之前关系的核心部分，即部分宽度幅度的统计分布，并从简单的模型中估计了其特征参数。
