Non-abelian inverse anderson transitions

W Zhang, H Wang, H Sun, X Zhang - Physical Review Letters, 2023 - APS
Inverse Anderson transitions, where the flat-band localization is destroyed by disorder, have
been wildly investigated in quantum and classical systems in the presence of Abelian gauge …

Anderson localization transition in disordered hyperbolic lattices

A Chen, J Maciejko, I Boettcher - Physical Review Letters, 2024 - APS

Hyperbolic lattices are a new type of synthetic materials based on regular tessellations in
non-Euclidean spaces with constant negative curvature. While so far, there has been …

Higher-order topological hyperbolic lattices

YL Tao, Y Xu - Physical Review B, 2023 - APS
A hyperbolic lattice allows for any p-fold rotational symmetry, in stark contrast to a two-

Hyperbolic non-Abelian semimetal

T Tummuru, A Chen, PM Lenggenhager, T Neupert… - Physical Review Letters, 2024 - APS
We extend the notion of topologically protected semi-metallic band crossings to hyperbolic
lattices in a negatively curved plane. Because of their distinct translation group structure …
