[HTML][HTML] Wave transport in 1D stealthy hyperuniform phononic materials made of non-resonant and resonant scatterers

V Romero-García, É Chéron, S Kuznetsova, JP Groby… - APL Materials, 2021 - pubs.aip.org
Stealthy hyperuniform point patterns are characterized by a vanishing spatial Fourier
transform around the origin of the reciprocal vector space. The long-range point density …

[HTML][HTML] Quantum-state transfer through long-range correlated disordered channels

GMA Almeida, FABF de Moura, ML Lyra - Physics Letters A, 2018 - Elsevier
We study quantum-state transfer in XX spin-1/2 chains where both communicating spins are
weakly coupled to a channel featuring disordered on-site magnetic fields. Fluctuations are …

Interplay of different environments in open quantum systems: Breakdown of the additive approximation

GG Giusteri, F Recrosi, G Schaller, GL Celardo - Physical Review E, 2017 - APS
We analyze an open quantum system under the influence of more than one environment: a
dephasing bath and a probability-absorbing bath that represents a decay channel, as …

Non-Hermitian Hamiltonian approach to quantum transport in disordered networks with sinks: Validity and effectiveness

GG Giusteri, F Mattiotti, GL Celardo - Physical Review B, 2015 - APS
We investigate the validity of the non-Hermitian Hamiltonian approach in describing
quantum transport in disordered tight-binding networks connected to external environments …

Information entropy of tight-binding random networks with losses and gain: Scaling and universality

CT Martínez-Martínez, JA Méndez-Bermúdez - Entropy, 2019 - mdpi.com
We study the localization properties of the eigenvectors, characterized by their information
entropy, of tight-binding random networks with balanced losses and gain. The random …

Noise, delocalization, and quantum diffusion in one-dimensional tight-binding models

E Gholami, ZM Lashkami - Physical Review E, 2017 - APS
As an unusual type of anomalous diffusion behavior, namely (transient) superballistic
transport, has been experimentally observed recently, but it is not yet well understood. In this …

Ballistic transport in aperiodic Labyrinth tiling proven through a new convolution theorem

F Sánchez, V Sánchez, C Wang - The European Physical Journal B, 2018 - Springer
In this article, we report a distinct convolution theorem developed for the Kubo-Greenwood
formula in Labyrinth tiling by transforming the two-dimensional lattice into a set of …

Resonant Anderson localization in segmented wires

C Estarellas, L Serra - Physical Review E, 2016 - APS
We discuss a model of random segmented wire, with linear segments of two-dimensional
wires joined by circular bends. The joining vertices act as scatterers on the propagating …

Anderson localization of Bogoliubov excitations on quasi‐1D strips

C Gaul, P Lugan, CA Müller - Annalen der Physik, 2015 - Wiley Online Library
Anderson localization of Bogoliubov excitations is studied for disordered lattice Bose gases
in planar quasi–one‐dimensional geometries. The inverse localization length is computed …
