The recent realization of a ``L\'evy glass'' (a three-dimensional optical material with a L\'evy distribution of scattering lengths) has motivated us to analyze its one-dimensional analog: A linear chain of barriers with independent spacings $s$ that are L\'evy distributed: $p(s)\ensuremath{\propto}{s}^{\ensuremath{-}1\ensuremath{-}\ensuremath{\alpha}}$ for $s\ensuremath{\rightarrow}\ensuremath{\infty}$. The average spacing diverges for $0l\ensuremath{\alpha}l1$. A random walk along such a…

Photonic heterostructures with Lévy-type disorder: Statistics of coherent transmission
We study the electromagnetic transmission $T$ through one-dimensional (1D) photonic heterostructures whose random layer thicknesses follow a long-tailed L\'evy-type distribution. Based on recent
Large Fluctuations and Transport Properties of the L\'evy-Lorentz gas
The Levy-Lorentz gas describes the motion of a particle on the real line in the presence of a random array of scattering points, whose distances between neighboring points are heavy-tailed i.i.d.
L\'evy walks
Random walk is a fundamental concept with applications ranging from quantum physics to econometrics. Remarkably, one specific model of random walks appears to be ubiquitous across many fields as a
Discrete- and continuous-time random walks in 1D L\'evy random medium
A Lévy random medium, in a given space, is a random point process where the distances between points, a.k.a. targets, are long-tailed. Random walks visiting the targets of a Lévy random medium have
Conductance of one-dimensional quantum wires with anomalous electron wave-function localization
We study the statistics of the conductance $g$ through one-dimensional disordered systems where electron wavefunctions decay spatially as $|\psi| \sim \exp (-\lambda r^{\alpha})$ for $0 $ and the

Lévy-type diffusion on one-dimensional directed Cantor graphs.
It is demonstrated that local and average measurements can display different asymptotic behavior, and the analytic results are compared to the numerical solution of the master equation of the process.
Information-Length Scaling in a Generalized One-Dimensional Lloyd’s Model
This model serves as a generalization of 1D Lloyd’s model and demonstrates that the information length β of the eigenfunctions follows the scaling law β=γx/(1+γx), with x=ξ/L and γ≡γ(α).
Distribution of the conductance of a linear chain of tunnel barriers with fractal disorder
Distributions of the conductance G of a long quantum wire with the fractal distribution of barriers have been obtained in the successive incoherent tunneling regime. The asymptotic behavior (in the
