Multifractality of growing surfaces.

We have carried out large-scale computer simulations of experimentally motivated (1+1)-dimensional models of kinetic surface roughening with power-law-distributed amplitudes of uncorrelated noise. The appropriately normalized qth-order correlation function of the height differences c q (x)= shows strong multifractal scaling behavior up to a crossover length depending on the system size, i.e., c q (x)∼x qHq , where H q is a continuously changing nontrivial function
