| Research Abstract |
We consider the distribution of eigenvalue and eigenfunction on the localized region of the random Schroednger operator on d-dimensional square lattice. We showed that, (1) they are uniformly distributed, as a whole, (2) they obey Poisson distribution in the natural scaling limit, and (3) they are repulsive under smaller scaling. Moreover, if we have Minami's estimate, the same results also hold for the random Schrodeinger operaors on the continuum.
