Absence of mobility edges in mosaic Wannier-Stark lattices

S Longhi - Physical Review B, 2023 - APS
Mobility edges, separating localized from extended states, are known to arise in the single-
particle energy spectrum of certain one-dimensional models with quasiperiodic disorder …

Driving-induced multiple -symmetry breaking transitions and reentrant localization transitions in non-Hermitian Floquet quasicrystals

L Zhou, W Han - Physical Review B, 2022 - APS
The cooperation between time-periodic driving fields and non-Hermitian effects could
endow systems with distinctive spectral and transport properties. In this paper, we uncover …

Two-dimensional vertex-decorated Lieb lattice with exact mobility edges and robust flat bands

Y Wang, L Zhang, Y Wan, Y He, Y Wang - Physical Review B, 2023 - APS
The mobility edge (ME) that marks the energy separating extended and localized states is a
most important concept in understanding the metal-insulator transition induced by …

Localization, multifractality, and many-body localization in periodically kicked quasiperiodic lattices

Y Zhang, B Zhou, H Hu, S Chen - Physical Review B, 2022 - APS
We study the combined effect of quasiperiodic disorder, driven, and interaction in the
periodically kicked Aubry-André model. In the noninteracting limit, by analyzing the …

Multiple localization transitions and novel quantum phases induced by a staggered on-site potential

R Qi, J Cao, XP Jiang - Physical Review B, 2023 - APS
We propose a one-dimensional generalized Aubry-André-Harper (AAH) model with off-
diagonal hopping and staggered on-site potential. We find that the localization transitions …

Quasiperiodicity hinders ergodic Floquet eigenstates

M Gonçalves, P Ribeiro, IM Khaymovich - Physical Review B, 2023 - APS
Quasiperiodic systems in one dimension can host nonergodic states, eg, states localized in
position or momentum. Periodic quenches within localized phases yield Floquet eigenstates …

Reentrant delocalization transition in one-dimensional photonic quasicrystals

S Vaidya, C Jörg, K Linn, M Goh, MC Rechtsman - Physical Review Research, 2023 - APS
Waves propagating in certain one-dimensional quasiperiodic lattices are known to exhibit a
sharp localization transition. We theoretically predict and experimentally observe that the …

Extended critical phase in quasiperiodic quantum Hall systems

JF Karcher, R Vasseur, S Gopalakrishnan - Physical Review B, 2024 - APS
We consider the effects of quasiperiodic spatial modulation on the quantum Hall plateau

Level-spacing distribution of localized phases induced by quasiperiodic potentials

C Yang, Y Wang - Physical Review B, 2024 - APS
Level statistics is an important quantity for exploring and understanding localized physics.
The level-spacing distribution (LSD) of the disordered localized phase follows Poisson …

Mobility edges and critical regions in a periodically kicked incommensurate optical Raman lattice

Y Wang - Physical Review A, 2022 - APS
Conventionally the mobility edge (ME) separating extended states from localized ones is a
central concept in understanding Anderson localization transition. The critical state, being …
