Hello, I am doing my undergraduate in the dept of 'mechanical design of intelligent systems' in Japan. During the fourth year we dont have any lectures and just work on research and our thesis. My field of research for the whole year will be molecular dynamics. Although this field uses Newtonian mechanics, i have become increasingly interested in quantum physics and spend most of my free time reading up on all the theoritical mathematics and physics involved. I would like to apply for a physics graduate program and am not sure as to which department will be most suitable considering my field of research. I am planning on appying for a fulbright this April so i also need to explain why I will be shifting fields. Any input would be much appreciated. Sorry to have made it long.
