纳米结构中的新输运现象：道路网络中Braess悖论的介观模拟
A new transport phenomenon in nanostructures: A mesoscopic analog of the Braess paradox encountered in road networks
摘要：
Braess悖论，以流量和其他经典网络而闻名，在于这样一个事实，即在拥塞的网络中添加新路由以缓解拥塞可能会违反直觉地降低整体网络性能。最近，我们将Braess佯谬的概念扩展到半导体介观网络，其输运性质由量子物理控制。在本文中，我们从理论上证明，在经典系统中，拥塞在介观网络中的Braess悖论的发生中起着关键作用。
英文摘要：
The Braess paradox, known for traffic and other classical networks, lies in the fact that adding a new route to a congested network in an attempt to relieve congestion can counter-intuitively degrade the overall network performance. Recently, we have extended the concept of Braess paradox to semiconductor mesoscopic networks, whose transport properties are governed by quantum physics. In this paper, we demonstrate theoretically that, alike in classical systems, congestion plays a key role in the occurrence of a Braess paradox in mesoscopic networks.
