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 …

Conventional superconductivity in quasicrystals

RN Araújo, EC Andrade - Physical Review B, 2019 - APS
Motivated by a recent experimental observation of superconductivity in the Al-Zn-Mg
quasicrystal, we study the low-temperature behavior of electrons moving in the …

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 …

Quasiperiodic pairing in graphene quasicrystals

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 …

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 …

Abstract Magnetism of Tsai-type 1/1 approximants has been extensively investigated for the
last decade. The experimental results on Tsai-type approximants are reviewed and the …

Quantum phase transition between hyperuniform density distributions
