【 摘 要 】

We reconsider the recently proposed connection between density of states in the so-called non-Hermitian quantum mechanics and the localization length for a particle moving in random potential. We argue that it is indeed possible to find the localization length from the density of states of anon-Hermitian random Hamiltonian. However, finding the density of states of a non-Hermitian random Hamiltonian remains an open problem, contrary to previous findings in the literature. [S0163-1829(98)05144-3].
