Multifractal critical chaos generated by two interacting particles in a disordered chain: Anderson model

It is shown, using data of numerical simulations performed by different aut hors, that multifractal chaos generated by two interacting particles in a d isordered chain (in the frames of the Anderson model) belongs to the same c lass of multifractal chaotic processes as critical chaos generated by the m ap x(n)+1 = 1 - a\x(n)\(z) via the Feigenbaum scenario. Moreover, a single parameter - multifractal critical index - characterizing this class, takes the same value for both the Anderson quantum chaos and for the universal cr itical chaos generated by the map x(n)+1 = 1- a\x(n)\(3).
