Hyperuniformity of quasicrystals [PDF]
Physical Review B, 2017 Hyperuniform systems, which include crystals, quasicrystals and special disordered systems, have attracted considerable recent attention, but rigorous analyses of the hyperuniformity of quasicrystals have been lacking because the support of the spectral intensity is dense and discontinuous.

Quantum Spin Hall Effect and Spin Bott Index in a Quasicrystal Lattice. [PDF]
Physical Review Letters, 2018 Despite the rapid progress in the field of the quantum spin Hall (QSH) effect, most of the QSH systems studied up to now are based on crystalline materials. Here we propose that the QSH effect can be realized in quasicrystal lattices (QLs).

Image Sampling with Quasicrystals [PDF]
, 2009 We investigate the use of quasicrystals in image sampling. Quasicrystals produce space-filling, non-periodic point sets that are uniformly discrete and relatively dense, thereby ensuring the sample sites are evenly spread out throughout the sampled image.

Dodecagonal bilayer graphene quasicrystal and its approximants [PDF]
npj Computational Materials, 2019 Dodecagonal bilayer graphene quasicrystal has 12-fold rotational order but lacks translational symmetry which prevents the application of band theory. In this paper, we study the electronic and optical properties of graphene quasicrystal with large-scale
