Multifractality of eigenfunctions in spin chains
Published 21 May 2012 in cond-mat.stat-mech, math-ph, and math.MP | (1205.4541v1)
Abstract: We investigate different one-dimensional quantum spin-1/2 chain models and by combining analytical and numerical calculations prove that their ground state wave functions in the natural spin basis are multifractals with, in general, non-trivial fractal dimensions.
