Tulio O. Carvalho, Cesar R. de Oliveira Hybrid Quasicrystals, Transport and Localization in Products of Minimal Sets (294K, pdf) ABSTRACT. We consider convex combinations of finite-valued almost periodic sequences (mainly substitution sequences) and put them as potentials of one-dimensional tight-binding models. We prove that these sequences are almost periodic. We call such combinations {\em hybrid quasicrystals} and these studies are related to the minimality, under the shift on both coordinates, of the product space of the respective (minimal) hulls. We observe a rich variety of behaviors on the quantum dynamical transport ranging from localization to transport.
