Quantum criticality and Kibble-Zurek scaling in the Aubry-André-Stark model

EW Liang, LZ Tang, DW Zhang - Physical Review B, 2024 - APS
We explore quantum criticality and Kibble-Zurek scaling (KZS) in the Aubry-André-Stark
(AAS) model, where the Stark field of strength ɛ is added onto the one-dimensional …

Nonequilibrium dynamics of the localization-delocalization transition in the non-Hermitian Aubry-André model

LJ Zhai, GY Huang, S Yin - Physical Review B, 2022 - APS
In this paper, we investigate the driven dynamics of the localization transition in the non-
Hermitian Aubry-André model with the periodic boundary condition. Depending on the …

Hybrid scaling properties of the localization transition in a non-Hermitian disordered Aubry-André model

YM Sun, XY Wang, LJ Zhai - Physical Review B, 2024 - APS
In this paper, we study the critical behaviors in the non-Hermitian disorder Aubry-André
(DAA) model, and we assume the non-Hermiticity is introduced by nonreciprocal hop** …

Dynamical evolution in a one-dimensional incommensurate lattice with symmetry

Z Xu, S Chen - Physical Review A, 2021 - APS
We investigate the dynamical evolution of a parity-time (PT) symmetric extension of the
Aubry-André (AA) model, which exhibits the coincidence of a localization-delocalization …

Cascade of the delocalization transition in a non-Hermitian interpolating Aubry-André-Fibonacci chain

LJ Zhai, GY Huang, S Yin - Physical Review B, 2021 - APS
In this paper, the interplay of the non-Herimiticity and the cascade of delocalization transition
in a quasiperiodic chain are studied. The study is applied in the non-Hermitian interpolating …

Localization-driven quantum sensing

A Sahoo, U Mishra, D Rakshit - Physical Review A, 2024 - APS
We show that the delocalization-localization transition in quantum many-body (QMB)
systems are a compelling quantum resource for achieving quantum-enhanced sensitivity in …

Topological defect formation in a phase transition with tunable order

F Suzuki, WH Zurek - Physical Review Letters, 2024 - APS
The Kibble-Zurek mechanism (KZM) describes the nonequilibrium dynamics and topological
defect formation in systems undergoing second-order phase transitions. KZM has found …

Tensor network simulation of the quantum Kibble-Zurek quench from the Mott to the superfluid phase in the two-dimensional Bose-Hubbard model

J Dziarmaga, JM Mazur - Physical Review B, 2023 - APS
Quantum simulations of the Bose-Hubbard model (BHM) at commensurate filling can follow
spreading of correlations after a sudden quench for times long enough to estimate their …

Family-Vicsek dynamical scaling and Kardar-Parisi-Zhang-like superdiffusive growth of surface roughness in a driven one-dimensional quasiperiodic model

S Aditya, N Roy - Physical Review B, 2024 - APS
The investigation of the dynamical universality classes of quantum systems is an important,
and rather less explored aspect of nonequilibrium physics. In this paper, considering the out …

Quantum criticality in the disordered Aubry-André model

X Bu, LJ Zhai, S Yin - Physical Review B, 2022 - APS
In this paper, we explore quantum criticality in the disordered Aubry-André (AA) model. For
the pure AA model, it is well known that it hosts a critical point separating an extended phase …
