AI 中文摘要
光驱动隐花色素蛋白还原产生的自由基对构成了一种自旋相关机制，伴有电偶极矩且对外部磁场敏感。本研究在量子力学框架内，研究了地球静磁场和随时间变化的磁场噪声对自由基对电偶极矩的同时影响。从不同角度探讨了外部磁场在不同频率和强度下的影响。系统行为对外部磁场频率和强度的敏感性，在磁场与地球静磁场夹角变化时差异很大。还研究了环境噪声影响下的敏感性。两个磁场分量的相对空间取向在电偶极矩的时间演化中起重要作用。对特定相对取向（如24度）的深入讨论表明，基于偶极矩的自由基对量子模型与鸟类行为研究结果一致。这些发现为自由基对模型对磁场组合的敏感性提供了新见解，可能有助于全面理解磁受体现象和推动生物启发式磁传感器的发展。
英文摘要
Radical pairs induced by light-driven reduction of cryptochrome protein constitute a spin dependent mechanism that is accompanied by an electric dipole moment and is found to be sensitive to external magnetic fields. In this research, to investigate for the further proof of such model, the simultaneous effect of the Earth's static magnetic field and the time-dependent magnetic field noise on the electric dipole moment of the radical pair has been studied within the quantum mechanical framework. The effect of the external magnetic field discussed in different angles regarding the Earth magnetic field within various frequencies and magnitudes. The sensitivity of the system behavior to the external magnetic field frequencies and magnitudes, vastly differs among the changes in the magnetic field angle to the Earth's static field. Furthermore, the sensitivity studied under the effect of the environmental noise. The relative spatial orientation of the two magnetic field components plays an important role in the time evolution of the electric dipole moment. Also, deeper discussions on specific relative orientations of the external magnetic fields, such as 24 degree, shows that the quantum model of radical pairs which is based on dipole moment, is in agreement with the results of the birds behavorial studies. These findings provide new insights into the sensitivity of the radical pair model to the combination of magnetic fields and may contribute to a comprehensive understanding of the phenomenon of magnetoreception and the advancement of bioinspired magnetic sensors.
