Abstract
The multifractal properties of electronic eigenstates at the metal-insulating transition of a two-dimensional disordered tight-binding model with spin-orbit interaction are investigated numerically. The correlation dimensions of the spectral measure D2 and of the fractal eigenstate D2 are calculated and shown to be related by D2=2D2. The exponent eta =0.35+or-0.05 describing the energy correlations of the critical eigenstates is found to satisfy the relation eta =2-D2.Keywords
