During my study at physics department in the beginning years, i had been
delving on physics analytical methods and experimental skills. but at the same time, i also found many physics problems were either toocomplicated to be written as an equation, or impossible to be solved due to their large amount of computation. one day by chance, i visited a computational physics laboratory, in which i was deeply impressed with computers great power in calculation and strong ability to graphics. from then on, i have been holding an idea that with the aid of computers, we will solve some physics problems, which are difficult to be dealt with by traditional methods.
1. creativity is the essential character for a successful researcher in the
spring of 2000, when i was studying atomic physics, i felt that states of atoms in equivalent electron configurations were rather difficult to obtain.
traditional methods to get it were both arduous and boring. not being content with that, i was determined to develop my own method. after two months of painstaking efforts, i finally came up with a kind of computing method and wrote a program in c language, which can easily obtain states of atoms in any equivalent electron configuration. the main idea of my program has been published in college physics, 12(2001), which is one of the most authoritative magazines in the field of physics science in china. the work involves a whole series of research activities, including defining the problem, conceiving computational methods, designing and modifying the programs, and writing the thesis, which were all done by myself. the process has strengthened my ability to think and work independently. it has also reinforced my belief that determination, diligence and creativity are indispensable to a successful researcher.
2. my experience at cai r&d center, f*** university with intense interest in simulation of physical process, i joined physics cai (computer aided uction) r&d center of f** university, a research center well known for developing physics cai software. through working in the center, i have improved my skills to simulate a physics phenomenon or to conduct experiments with the aid of computers. i was involved in producing solid state physics cai courseware web version, which had been put on the web site of the united nations educational, scientific and cultural organization (unesco), as a part of its project: unesco global science and technical education network (unesco-gsten). my main responsibility was to make most of its three-dimensional animation in the virtual reality modeling language (vrml). those days in physics cai r&d center taught me how to be a good team player. three of my classmates and i formed a group, in which views were exchanged about experiment simulation and anything related to cai. in the fall of 2000, we applied for the "scientific innovation fund of f*** university". after three rounds of competition, we succeeded in obtaining a first class grant of 3500rmb($500) for our project: the modern physics cai courseware. out of 80 groups in my university, only 9 won the award. we aimed to present physics pictures in the form of graphics and animation. it was our hope that the courseware can provide valuable assistance to students in their learning of modern physics. i am responsible for the simulation of some well-known experiments, such as rutherford scattering and compton effect. by now, the major part of the courseware has been completed and we will it on the national exhibition soon.
3. my independent research ability as a junior, i was among those students in my grade who first had the opportunity to take part in actual research. in september 2000, i joined the theoretical physics group to do research on magnetics under the guidance of prof. r** tao, a noted chinese scientist in this field. owing to the systematic theoretical learning and much practice in cai r&d center, i had then well prepared myself in magnetic research. i was once assigned to compute the magnetic resistance of a 32x32 ferromagnetic layer, pinned by an antiferromagnetic layer. i developed an application, which can monitor the magnetic resistance of the ferromagnetic layer when the angle of the pinning layer was changed. being familiar with fft (fast fourier transform), i managed to apply it to the process of computation, which was then accelerated significantly. as a result, the computable size of the ferromagnetic layer can be enlarged from 32x32 to 256x256. after changing the parameters, the results were enhanced, and i am currently amending the paper. my work has won the kind attention from prof. p** sheng, head of the department of physics at h*** university of science and technology. from august 8th, 2001 to august 21st, 2001, he invited me to his department to collaborate in magnetic resistance research. when i was in hong kong, the s** company, which specialized in designing and producing magnetic heads for hard disks, showed great interest in my giant magnetoresistance (gmr) simulation software. i talked at length with the companys engineer about the possibility to put my software into the industrial use. when simulating the magnetic loop of a ferromagnetic layer, i discovered several quantum states, which could be obtained by changing the magnetic field. because these new quantum states are all quite stable, they can be used to record information in multi-bits. at the 2001 fall meeting of chinas physical society, prof. tao was invited to make a presentation based on a paper entitled "multi-bits recording", of which i was labeled as the first author.
4. extracurricular activities my heavy academic load has never deterred me from taking part in extracurricular activities. as a member of class board in charge of physical exercises in my grade, i organized numerous sports
activities, such as "dormitory cup" of basketball game, ping-pong tournaments and so on. through these activities, i have improved my capability of leadership, organization and teamwork, which, combined with my intellectual vigor, should help make me ready for any challenges. i wish to pursue a phd degree in condensed matter physics, for its intrinsic beauty and practical perspective have fascinated me. attracted by the academic atmosphere and advanced research facilities you offer, i consider your school an ideal place for me. from the material you sent and your web site, i also find my research experience closely related to the academic field of some faculties, which convinced me that your department provides appropriate programs for me. as i have gained extensive experience in computational analysis and modeling, you may find me a competent student for the advanced research area i have mentioned. ultimately, i aim to devote myself to a science career, in which i can use my knowledge and skills in a creative and practical manner.
