论文摘要
克服纳米级疾病的有害作用非常困难，因为疾病会引起定位和指数抑制运输效率。在这里，我们通过利用远距离跳跃来推出在纳米系统中可以实现的小说和健壮的量子运输方式。我们证明，在有远距离跳跃，运输效率的情况下，纳米结构在起初呈指数级降低后，通过障碍[无序增强运输（DET）制度]增强，直到违反直觉，它可以达到与障碍无关的运输（DIT）制度，直到违反直觉，持续了多个级别的多个级数。为了启发我们的结果的相关性，我们证明了一个空腔中的发射器集合可以用有效的远程哈密顿式化学来描述。讨论了放置在光腔中的分子电线的特定情况，表明可以使用最新的实验设置达到DIT和DET状态。
Overcoming the detrimental effect of disorder at the nanoscale is very hard since disorder induces localization and an exponential suppression of transport efficiency. Here we unveil novel and robust quantum transport regimes achievable in nanosystems by exploiting long-range hopping. We demonstrate that in a 1D disordered nanostructure in the presence of long-range hopping, transport efficiency, after decreasing exponentially with disorder at first, is then enhanced by disorder [disorder-enhanced transport (DET) regime] until, counterintuitively, it reaches a disorder-independent transport (DIT) regime, persisting over several orders of disorder magnitude in realistic systems. To enlighten the relevance of our results, we demonstrate that an ensemble of emitters in a cavity can be described by an effective long-range Hamiltonian. The specific case of a disordered molecular wire placed in an optical cavity is discussed, showing that the DIT and DET regimes can be reached with state-of-the-art experimental setups.
