开放量子网络中的激发-输运:组态的影响

Excitation-transport in open quantum networks: The effects of configurations

James Cormican, Lorenzo Stella, Mauro Paternostro

摘要:

我们研究了环境辅助增强的激发传输效率通过网络的相互作用的量子粒子或网站。我们的研究揭示了网络配置的关键影响-特别是它的连接程度-对环境支持的增强量。特别是,我们发现一个显着的相互作用的直接和间接的连接之间的激励发送和接收站点。另一方面,非Markovianity引起的记忆轴承,有限大小的环境似乎并没有提供一个关键的资源,增强的兴奋传输机制。

英文摘要:

We study the environment-assisted enhancement of the excitation-transport efficiency across a network of interacting quantum particles or sites. Our study reveals a crucial influence of the network configuration - and especially its degree of connectivity - on the amount of environment-supported enhancement. In particular, we find a significant interplay of direct and indirect connections between excitation sending and receiving sites. On the other hand, the non-Markovianity induced by memory-bearing, finite sized environments does not seem to provide a critical resource for the enhanced excitation-transport mechanism.
