Lyapunov exponents in one-dimensional disordered systems with long-range memory.
The Lyapunov exponents for Anderson localization are studied in a one-dimensional disordered system. A random Gaussian potential with the power-law decay approximately 1/|x|q of the correlation function is considered. The exponential growth of the moments of the eigenfunctions and their derivative is obtained. Positive Lyapunov exponents, which determine the asymptotic growth rate, are found.
