Eigenfunction distribution for the Rosenzweig-Porter model

Quantum Physics 2018-10-03 v1 Mathematical Physics math.MP

Abstract

The statistical distribution of eigenfunctions for the Rosenzweig-Porter model is derived for the region where eigenfunctions have fractal behaviour. The result is based on simple physical ideas and leads to transparent explicit formulas which agree very well with numerical calculations. It constitutes a rare case where a non-trivial eigenfunction distribution is obtained in a closed form.
