Multifractality of Hamiltonians with power-law transfer terms
E. Cuevas
Abstract
Finite-size effects in the generalized fractal dimensions dq are investigated numerically. We concentrate on a one-dimensional disordered model with long-range random hopping amplitudes in both the strong- and the weak-coupling regime. At the macroscopic limit, a linear dependence of dq on q is found in both regimes for values of q 4g-1, where g is the coupling constant of the model.
