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 …

Quantized perfect transmission in graphene nanoribbons with random hollow adsorbates

JL Yu, Z Hou, IH Bhat, PJ Hu, JW Sun, XF Chen… - Physical Review B, 2024 - APS
Impurities exist inevitably in two-dimensional materials as they spontaneously adsorb onto
the surface during fabrication, usually exerting detrimental effects on electronic transport …

Disorder-induced phase transitions in double Weyl semimetals

J Zhang, F Wan, X Wang, Y Ding, L Liao, Z Chen… - Physical Review B, 2022 - APS
The double Weyl semimetal (DWSM) is a newly proposed topological material that hosts
Weyl points with chiral charge n= 2. The disorder effect in DWSM is investigated by adopting …

Effects of dilution in a 2D topological magnon insulator

MS Oliveira, TVC Antão, EV Castro, N Peres - arXiv preprint arXiv …, 2023 - arxiv.org
We study the effect of diluting a two-dimensional ferromagnetic insulator hosting a
topological phase in the clean limit. By considering the ferromagnetic Heisenberg model in …

[PDF][PDF] Investigating topological properties of floquet quasi-one-dimensional systems

A Agrawal - 2023 - dspace.bits-pilani.ac.in
Photonics plays a pivotal role in advancing the field of topological insulators by enabling the
synthetic preperation of these materials, which may not exist naturally. The quasi-one …
