Lyapounov exponent and density of states of a one-dimensional non-Hermitian Schroedinger equation

Bernard Derrida, Jesper Lykke Jacobsen, Reuven Zeitak

We calculate, using numerical methods, the Lyapounov exponent gamma(E) and the density of states rho(E) at energy E of a one-dimensional non-Hermitian Schroedinger equation with of…
