Chaos-based potentials are defined and implemented in the one-dimensional tight-binding model as a way of simulating disorder-controlled crystalline lattices. In this setting, disorder is handled with the aid of the chaoticity parameter. The inverse participation ratio (IPR) probes the response of the system to three different such potentials and shows consistent agreement with results given by the Lyapunov exponent $$\mathrm{Ly}$$Ly: the greater $$\mathrm{Ly}(r)$$Ly(r) for the chaotic sequence… 



Unusual scaling of the spectrum in a deterministic aperiodic tight-binding model.

Local and global scaling properties of the integrated density of states of the tight-binding Rudin-Shapiro model are numerically derived by investigating the dependence of the bandwidths of its

The one-dimensional tight-binding model with site energies arranged in the Thue-Morse sequence is studied, to show the characteristics of eigenstates, and a multifractal analysis on the wave functions is performed.

Trace-map invariant and zero-energy states of the tight-binding Rudin-Shapiro model.

It is proved that an infinite sequence of values of the on-site potential exists such that for each of these the energy E=0 lies in the spectrum of the periodic approximants corresponding to the even generations of the chain.

Persistent current and Drude weight in one-dimensional rings with substitution potentials

Persistent currents and Drude weights are investigated using the tight-binding approximation to one-dimensional rings threaded by a magnetic flux and with the potential given by some almost-periodic

It is shown that the IPR distribution function is scale invariant, with a power-law asymptotic "tail," which implies that the fractal dimensions D(q) are nonfluctuating quantities, contrary to a recent claim in the literature.

It is shown that the spectrum consists of absolutely continuous parts and singular continuous parts.

Characterization of spectrum and eigenvectors of the Schrödinger operator with chaotic potentials

Chaotic sequences are sequences generated by chaotic maps. A particle moving in a one-dimensional space has its behavior modeled according to the time-independent Schrodinger equation. The

Localization of electrons and electromagnetic waves in a deterministic aperiodic system.

A study of the optical properties of the Rudin-Shapiro dielectric multilayer shows strong similarities with the behavior of the disordered multilayers regarding the development of gaps in the transmission spectra.

Intermittency Route to Strange Nonchaotic Attractors

Strange nonchaotic attractors (SNA) arise in quasiperiodically driven systems in the neighborhood of a saddle-node bifurcation whereby a strange attractor is replaced by a periodic (torus) attractor.

Analytical results for scaling properties of the spectrum of the Fibonacci chain.

The approximate renormalisation group found by Qiu Niu and Franco Nori for a tight-binding hamiltonian on the Fibonacci chain is solved and analytically as completely as possible the spectral properties of this model are characterized.
