Phase transitions in a non-Hermitian Aubry-André-Harper model

S Longhi - Physical Review B, 2021 - APS
The Aubry-André-Harper model provides a paradigmatic example of aperiodic order in a
one-dimensional lattice displaying a delocalization-localization phase transition at a finite …

Multiparticle localization for disordered systems on continuous space via the fractional moment method

M Fauser, S Warzel - Reviews in Mathematical Physics, 2015 - World Scientific
We investigate the spectral and dynamical localization of a quantum system of n particles on
ℝd which are subject to a random potential and interact through a pair potential which may …

Chern numbers, localisation and the bulk-edge correspondence for continuous models of topological phases

C Bourne, A Rennie - Mathematical Physics, Analysis and Geometry, 2018 - Springer
In order to study continuous models of disordered topological phases, we construct an
unbounded Kasparov module and a semifinite spectral triple for the crossed product of a …

Large block properties of the entanglement entropy of free disordered fermions

A Elgart, L Pastur, M Shcherbina - Journal of Statistical Physics, 2017 - Springer
We consider a macroscopic disordered system of free d-dimensional lattice fermions whose
one-body Hamiltonian is a Schrödinger operator H with ergodic potential. We assume that …

One-dimensional discrete Dirac operators in a decaying random potential I: spectrum and dynamics

O Bourget, GR Moreno Flores, A Taarabt - Mathematical Physics, Analysis …, 2020 - Springer
We study the spectrum and dynamics of a one-dimensional discrete Dirac operator in a
random potential obtained by damping an iid environment with an envelope of type n− α for …

On the analogues of Szegő's theorem for ergodic operators

W Kirsch, LA Pastur - Sbornik: Mathematics, 2015 - iopscience.iop.org
Szegő's theorem on the asymptotic behaviour of the determinants of large Toeplitz matrices
is generalized to the class of ergodic operators. The generalization is formulated in terms of …

One-dimensional discrete Anderson model in a decaying random potential: From ac spectrum to dynamical localization

O Bourget, GRM Flores, A Taarabt - Spectral Theory and Mathematical …, 2020 - Springer
We consider a one-dimensional Anderson model where the potential decays in average like
n− α, α> 0. This simple model is known to display a rich phase diagram with different kinds of …

Random Schr\" odinger Operators on discrete structures

C Rojas-Molina - arXiv preprint arXiv:1710.02293, 2017 - arxiv.org
The Anderson model serves to study the absence of wave propagation in a medium in the
presence of impurities, and is one of the most studied examples in the theory of quantum …

Non-Hermitian topological photonics in coupled optical fibre loops

S Weidemann - 2023 - inis.iaea.org
[en] In this thesis, the interplay between topology, disorder, and dissipation is investigated
both theoretically and experimentally. Embedded into the field of non-Hermitian physics, one …
