Efficient quantum transport in disordered Floquet networks

Hlér Kristjánsson, Jonathan Brugger, Gabriel Dufour, Christian Scheppach, Andreas Buchleitner

AI总结:

研究受光合复合物启发,提出通过无序网络进行高效量子输运机制,依赖网络位点间耦合与外部振动驱动相互作用,利用弗洛凯 - 希尔伯特空间反射对称性等原则确保近乎完美输运。

AI中文摘要:

受光合复合物启发,我们提出一种通过具有可变在位能量的无序网络进行快速高效量子输运的机制。该机制依赖于网络的位点间耦合与外部振动驱动之间的相互作用。展示了两条设计原则可确保尽管存在无序仍能实现近乎完美的输运,即弗洛凯 - 希尔伯特空间中的反射对称性以及弗洛凯态主导二重态或三重态的存在。

英文摘要:

We propose a mechanism for fast and efficient quantum transport through disordered networks with variable on-site energies, inspired by photosynthetic complexes. The mechanism relies on an interplay between inter-site couplings of the network and driving by external vibrations. Two design principles are shown to ensure close-to-perfect transport despite the disorder, namely a reflection symmetry in Floquet-Hilbert space and the existence of a dominant doublet or triplet of Floquet states.
