Anderson localization in dissipative lattices

S Longhi - Annalen der Physik, 2023 - Wiley Online Library
Anderson localization predicts that wave spreading in disordered lattices can come to a
complete halt, providing a universal mechanism for dynamical localization. In the one …

Robust Anderson transition in non-Hermitian photonic quasicrystals

S Longhi - Optics Letters, 2024 - opg.optica.org
Anderson localization, ie, the suppression of diffusion in lattices with a random or
incommensurate disorder, is a fragile interference phenomenon that is spoiled out in the …

Dephasing-induced mobility edges in quasicrystals

S Longhi - Physical Review Letters, 2024 - APS
Mobility edges (ME), separating Anderson-localized states from extended states, are known
to arise in the single-particle energy spectrum of certain one-dimensional lattices with …

Dephasing-induced jumps in non-Hermitian disordered lattices

ET Kokkinakis, KG Makris, EN Economou - arxiv preprint arxiv …, 2024 - arxiv.org
Changes in the wavefunction's phase during propagation in a random Hermitian lattice, a
process known as dephasing, results in diffusion rather than Anderson localization …

Spectra of generators of Markovian evolution in the thermodynamic limit: From non-Hermitian to full evolution via tridiagonal Laurent matrices

FR Klausen, AH Werner - arxiv preprint arxiv:2206.09879, 2022 - arxiv.org
We determine spectra of single-particle translation-invariant Lindblad operators on the
infinite line. In the case where the Hamiltonian is given by the discrete Laplacian and the …

Quantum simulation of the dephasing Anderson model

M Hunter-Gordon, Z Szabó, RA Nyman, F Mintert - Physical Review A, 2020 - APS
The interplay of Anderson localization and decoherence results in intricate dynamics that is
notoriously difficult to simulate on classical computers. We develop the framework for a …
