Density of states in the non-hermitian Lloyd model

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 a non-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.
