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 …

Localization with non-Hermitian off-diagonal disorder
A Saha, D Rakshit - arXiv preprint arXiv:2310.13744, 2023 - arxiv.org
In this work we discuss a non-Hermitian system described via a one-dimensional single-
particle tight-binding model, where the non-Hermiticity is governed by a random nearest …

Stark localization near Aubry-Andr\'{e} criticality
A Sahoo, A Saha, D Rakshit - arXiv preprint arXiv:2404.14971, 2024 - arxiv.org
In this work we investigate the Stark localization near the Aubry-Andr\'{e}(AA) critical point.
We study system-dependent parameters, such as localization length, inverse participation …
