Multifractality of eigenfunctions in spin chains    [PDF]

Yasar Yilmaz Atas, Eugene Bogomolny

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.
