论文摘要
对于全球科学家来说，鸟类导航的机制是一个重要的问题。最著名的候选人之一是激进对机理（RPM），它表明，通过检测化学反应的产物数量来实现禽类导航，这些化学反应的量具有不同的单元和三重态旋转状态。基于该理论，我们通过改变磁场的耦合强度和方向来探索单线重组产物的量。我们模型中的激进对与Lipkin-Meshkov-Glick（LMG）浴室相结合，该浴场提出了在量子相变（QPT）点时的吸引力结果，尤其是当磁场与该对的原始方向平行时。根据我们的建议方法之一，我们发现QPT点中最弱的导航能力。当磁场垂直于激进对和浴室的平面时，我们发现在我们的哈密顿量中不变子空间，这将大大加快我们的计算。我们的结果可以帮助探索人工禽类导航的设计原理。
The mechanism of avian navigation is an important question for global scientists. One of the most famous candidates is the radical pair mechanism (RPM), which shows that avian navigation is achieved by detecting the amount of products from chemical reactions, which exhibit different properties for singlet and triplet spin states. Based on the theory, we explore the amount of the the singlet recombination product by changing the coupling strength and direction of the magnetic field. The radical pair in our model is coupled with a Lipkin-Meshkov-Glick (LMG) bath, which proposes attractive results at quantum phase transition (QPT) point, especially when the magnetic field is parallel with the original direction of the pair. We find weakest navigation ability in QPT point according to one of our proposing methods. And we find invariant subspace in our Hamiltonian when the magnetic field is vertical to the plane of the radical pair and the bath, which will greatly speed up our calculation. Our results could help the exploration of the design principle of artificial avian navigation.
