Utilization of Renormalized Mean-Field Theory upon Novel Quantum Materials

Abstract

To finish a thesis co-advised by two parties is not a easy task. I can never accomplish this without being helped by a lot of people. Among them, first, I need to show my 100 percent gratitude to Dr. T.K. Lee, who granted me this opportunity of conducting research under his supervision. Besides the knowledge I have learned and the training I obtained, the most important spirits I learned from him are the integrity and diligence that a scientist should possess. After occupying a same position and doing the same job for a long time, it is easy for a person to feel exhausted and therefore lose interest. But as a scientist it is a sign of danger because what we are doing for lifetime is the pursuit for the truth and reality. That can be the burden but also the joy. In these days collaborating with Dr. Lee, despite the hard time when we tried to settle down on the same page, I have never saw him lose interest in Physics. Considering how busy he is with also a administrative position as the director of Institute of Physics, Academia Sinica, this is even more difficult to keep the passion like he does. Those spirits I learned from him will be my lifetime treasure no matter if I succeed in becoming a scholar in the future. Second, Dr. Didier Poilblanc also taught me a lot. The academic environment in Taiwan is not that open compared with Europe where scientists from difference countries can easily meet each other. Thanks for his acceptance of my request of a joint-degree thesis, I got the chance to conduct research in France and therefore obtained many opportunities discussing physical topics with other outstanding scientists. To learn how to express my idea properly v is crucial in becoming an independent physicist and during the time in France those are among all what I got to learn the most. I think it is fair to say that he led me on the track of becoming an independent researcher from just a apprentice of physics. Thus, I want to thank Didier for not only teaching me a lot of academic knowledge, but also those chances he granted me for interacting with other experts in this field. Plus, our co-workers mean a lot to me since they were willing to spare time collaborating with us upon certain issues. I would like to thank Dr.
