Multifractality occurs in the local density of states (LDOS) in disordered electronic systems near a metal-insulator transition, and despite an abundance of theoretical studies, experimental analyses are rare. Here, using scanning tunneling microscopy, the authors investigate the correlations of the LDOS and multifractal spectra for Sn/Si monolayers and connect the localization patterns of disordered electronic systems with the Weyl group symmetry of nonlinear sigma-models.
