High-angular-momentum topological superconductivities in twisted bilayer quasicrystal systems

YB Liu, Y Zhang, WQ Chen, F Yang - Physical Review B, 2023 - APS
The electron states in the quasicrystal (QC) are hot topics recently. While previous attentions
were focused on such intrinsic QCs as the Penrose lattice, the recent “twistronics” provides …

Topological magnetic textures and long-range orders in terbium-based quasicrystal and approximant

S Watanabe - Proceedings of the National Academy of …, 2021 - National Acad Sciences
The quasicrystal (QC) possesses a unique lattice structure with rotational symmetry
forbidden in periodic crystals. The electric property is far from complete understanding. It has …

Nematic superconductivity and its critical vestigial phases in the quasicrystal

YB Liu, J Zhou, F Yang - Physical Review Letters, 2024 - APS
We propose a general mechanism to realize nematic superconductivity (SC) and reveal its
exotic vestigial phases in the quasicrystal (QC). Starting from a Penrose-Hubbard model, our …

Superconductivity on a quasiperiodic lattice: Extended-to-localized crossover of Cooper pairs

S Sakai, N Takemori, A Koga, R Arita - Physical Review B, 2017 - APS
We study a possible superconductivity in quasiperiodic systems by portraying the issue
within the attractive Hubbard model on a Penrose lattice. Applying a real-space dynamical …

Antiferromagnetic order in the Hubbard model on the Penrose lattice

A Koga, H Tsunetsugu - Physical Review B, 2017 - APS
We study an antiferromagnetic order in the ground state of the half-filled Hubbard model on
the Penrose lattice and investigate the effects of quasiperiodic lattice structure. In the limit of …

Properties of the Ammann–Beenker Tiling and its Square Periodic Approximants

A Jagannathan, M Duneau - Israel Journal of Chemistry, 2024 - Wiley Online Library
Our understanding of physical properties of quasicrystals owes a great deal to studies of
tight‐binding models constructed on quasiperiodic tilings. Among the large number of …
