Dirac electrons in a dodecagonal graphene quasicrystal [PDF]
Science, 2018 Dirac fermions in quasicrystalline graphene Quasicrystal lattices, which can have rotational order but lack translational symmetry, can be used to explore electronic properties of materials between crystals and disordered solids. Ahn et al. grew graphene

Journal of High Energy Physics, 2023 Abstract We study the ground state of the low energy dense QCD with the assumption of chiral condensates of quarks. Under an external magnetic field, mesons could form soliton lattices via the chiral anomaly. For such scenarios, we present a unified description of pions and η meson with a U(2) field in the framework of the chiral ...

Crystallography of quasiperiodic moiré patterns in homophase twisted bilayers. [PDF]
Acta Crystallogr A Found AdvThe quasiperiodic nature of moiré patterns in homophase twisted bilayers is analyzed to understand the underlying basic periodicities and symmetries of homophase twisted bilayers built on any 2D structure.This paper discusses the geometric properties and symmetries of general moiré patterns generated by homophase bilayers twisted by rotation 2δ.

Layer-dependent topological phase in a two-dimensional quasicrystal and approximant [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance The behavior of electrons in solids is intimately related to symmetry and dimensionality, and it is the interaction of these two that dictates the topological properties of materials.

Tetracoordinated quasicrystals [PDF]
Physical Review B, 1991 Current model networks for amorphous Ge contain five-membered rings and pentagonal dodecahedra to explain why in the radial distribution function the third peak of the diamond structure is missing. By presenting an algorithm based on a decoration of the three-dimensional Penrose quasilattice, we prove that this local pentagonal symmetry can be extended
