| Summary: | 碩士 === 國立成功大學 === 航空太空工程學系 === 103 === Migration behavior is a seasonal regular activity of birds. Long-distance traveling with definite heading direction is the feature of this activity. From the observation of bird's behavior experiments, scientists discover that birds use plenty of methods to navigate. One of those navigation methods is using earth magnetic field that is the topic to be studied in this thesis. The ability of navigation using earth magnetic field is known as magnetoreception. Currently, a theory based on quantum mechanics reports that the magnetic field of Earth can indirectly affect some molecular chemical reactions of birds, and thereby change the direction of the flight of birds. The researchers called this chemical magnetoreception process radical pair mechanism.
We plan to use quantum mechanics to build a model for radical pairs system, and to analyze its characteristics. In addition, by the assistance of numerical simulation we will reveal how birds can utilize earth magnetic field to guide their flying path. Moreover, we propose an navigation magnetoreception artificial eyeball build by the artificial synthetic radical pair molecule. Finally, we try to apply quantum control to control the quantum state of radical pairs, and combining the artificial eyeball we mentioned, we plan to use quantum control to improve the performance of magnetoreception chemical compass.
