Abstract

We analyze ground state and spectral properties of the one-dimensional half-filled Holstein Hubbard model with respect to the Peierls-insulator to Mott-insulator transition, exploiting Lanczos diagonalization, density matrix renormal-ization, kernel polynomial expansion, and maximum entropy methods on the Hitachi SR8000-F1 supercomputer.
