标题： Feedback between interacting transport channels

摘要： 一种用于通过大量通道自主反馈控制粒子传输的模型被引入。 粒子之间的相互作用可能导致粒子数统计中的波动强烈抑制。 在平均场类型极限下，集体控制机制等价于与外部时钟的同步。 反馈信号在通道中的扩散传播表现出标度性，可以通过信息流进行量化，并例如在粒子噪声的谱函数中显现。 显示英文摘要

摘要： A model for autonomous feedback control of particle transport through a large number of channels is introduced. Interactions among the particles can lead to a strong suppression of fluctuations in the particle number statistics. Within a mean-field type limit, the collective control mechanism becomes equivalent to a synchronization with an external clock. The diffusive spreading of the feedback signal across the channels shows scaling, can be quantified via the flow of information, and shows up, e.g., in the spectral function of the particle noise.
