| Research Abstract |
The research on the formation of fractal patterns attracts much attention of physicists according to its universality and generality. To reveal the physical origin of the formation of fractal patterns, it has not been successful in terms of convertional approaches such as computer simulations. There has been numerous unsolved problems for this subject. The goal of the present research is to reveal the the physical origin of fractal pattern formation by means of employing quite new numerical techniques. Our goal is (1) to handle freely 10^7×10^7 matrices and (2) to apply our numerical algorithm to quantum and classical fractal structures. Our method is unique, different from other conventional methods, to map the eigenvalue problem to the problem of lattice vibrations. By applying this method, we have succeeded to obtain new results for our subject.
