| Research Abstract |
The aim of this research project is to develop the efficient algorithm for the eigenvalue analysis of very large matrices of [10^6×10^6], and computing dynamic correlation functions of the systems described by those matrices. In addition, we try to extend this numerical to apply for method non-Hermitian large-scale matrices. In these term, we have succeeded to develop the algorithm to use any type of large-scale matrices. We have also applied this algorithm to actual physical systems and demonstrated its surprising efficiency.
