Abstract
A multifractal analysis of wave functions in one-dimensional tight-binding systems with off-diagonal disorder is performed for eigenenergies near and at the center of the band. Numerical and analytical calculations for the latter state indicate the absence of multifractal properties for the space fluctuations of the corresponding probability distribution in those systems. The generalized Lyapunov exponents for the state at E=0 are obtained exactly. © 1988 The American Physical Society.
