停留时间分布作为区分量子输运不同路径的标志
Distribution of residence times as a marker to distinguish different pathways for quantum transport
摘要：
电子输运在纳米尺度系统中的传输是一个内在随机的量子力学过程。电流是由随机间隔分开的电子隧穿事件的时间序列。热噪声和量子噪声是这种随机性的两个来源。在本文中，我们使用量子主方程来考虑以下问题：（i）给定一个电子在某个特定的时间从源电极隧穿进入电子未被占据的系统，它是多久，直到电子隧道到漏电极离开电子未被占据的系统，那里没有中间隧穿事件（“隧道”路径）？(ii)假设一个电子在某个特定的时间从源极隧穿进入未被占据的系统，那么在没有中间隧穿事件（“一个”隧穿路径）的情况下，电子隧穿到漏极离开未被占据的系统需要多长时间？(iii)这些时间的分布是什么？我们发现，电子相关抑制“的”和“一个”电子隧穿路径之间的差异。
英文摘要：
Electron transport through a nanoscale system is an inherently stochastic quantum mechanical process. Electric current is a time series of electron tunnelling events separated by random intervals. Thermal and quantum noise are two sources of this randomness. In this paper, we used the quantum master equation to consider the following questions: (i) Given that an electron has tunnelled into the electronically unoccupied system from the source electrode at some particular time, how long is it until an electron tunnels out to the drain electrode to leave the system electronically unoccupied, where there were no intermediate tunnelling events ("the" tunnelling path)? (ii) Given that an electron has tunnelled into the unoccupied system from the source electrode at some particular time, how long is it until an electron tunnels out to the drain electrode to leave the system electronically unoccupied, where there were no intermediate tunnelling events ("an" tunnelling path)? (iii) What are the distributions of these times? We show that electron correlations suppress the difference between "the" and "an" electron tunnelling paths.
