论文摘要
这项工作研究了手性诱导的自旋选择性（CISS）对鸟类磁体受体的自由基对机理中量子自旋相干性的影响。此外，我们通过分析其与信号传导状态的产量的相关性来检查连贯性在鸟类指南针中的功能性作用。我们发现，从CISS中，整体相干性的相对熵和局部连贯性都会增加。但是，只有全球连贯性在禽指南针中表现出功利主义的作用。我们还分析了偶极相互作用与CISS的相互作用及其对自由基对相干性的影响。此外，我们分析了环境破裂的效果以及CISS。我们得出的结论是，高CISS导致全球连贯性与信号状态产量的高相关性。它证实，CISS在禽指南针中的敏感性和连贯性中都起着重要作用。
This work investigates the effect of chiral-induced spin selectivity (CISS) on quantum spin coherence in the radical pair mechanism of avian magnetoreception. Additionally, we examine the utilitarian role of coherence for the avian compass by analyzing its correlation with the yield of the signaling state. We find that both the relative entropy of global coherence and local coherence in the radical pair increases with CISS. However, only global coherence exhibit the utilitarian role for the avian compass. We also analyze the interplay of dipolar interaction with the CISS and their effect on the coherence of the radical pair. Further, we analyze the effect of environmental decoherence along with CISS. We conclude that a high CISS results in a high correlation of global coherence with signaling state yield. It confirms that CISS plays an important role both for compass sensitivity and coherence in the avian compass.
