Transport exponents of states with large support
  We extend results of Damanik and Tcheremchantsev on estimating transport exponents to initial states supported on more than one site. These general results for upper and lower bounds are then applied to several classes of models, including Sturmian, quiasi-periodic and substitution-generated potentials, and random polymer model.
