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
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 …

Quantum simulation of the dephasing Anderson model
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 …
