论文摘要
在本文中，我们研究了手性诱导的自旋选择性（CISS）对禽磁体受体的自由基对模型的影响。我们研究了旋转选择性对鸟类指南针灵敏度的影响。在此分析中，我们还考虑了偶极和交换相互作用，并观察它们与CISS的相互作用。我们发现CISS导致鸟类指南针灵敏度的多重增加。有趣的是，我们还观察到CISS可以抵消偶极相互作用的有害效应并提高系统敏感性。对玩具模型（仅1个核）和更一般的情况进行了分析，我们考虑了来自Cryptodolome自由基对系统的4-核。我们观察到CISS允许激进对模型具有更现实的速率，其灵敏度良好。我们还对功能窗口中行为实验中报道的鸟类指南针的功能窗口进行分析。我们找不到一个参数集，其中可以与CISS一起观察功能窗口。
In this paper, we investigate the effect of chiral-induced spin selectivity (CISS) on the radical pair model of avian magnetoreception. We examine the impact of spin selectivity on the avian compass sensitivity. In this analysis, we also consider the dipolar and exchange interactions and observe their interplay with CISS. We find that CISS results in multifold increase in avian compass sensitivity. Interestingly, we also observe that CISS can counter the deleterious effect of dipolar interaction and increase system sensitivity.The analysis has been performed for both the toy model (only 1 nucleus) and a more general case where we consider 4-nuclei from the cryptochrome radical pair system. We observe that the CISS allows the radical pair model to have a more realistic rate with good sensitivity. We also do analysis of functional window of avian compass reported in behavioral experiments in functional window. We could not find a parameter set where functional window can be observed along with CISS.
