Formation of a stable deacagonal quasicrystalline Al-Pd-Mn surface layer [PDF]
, 2001 We report the in situ formation of an ordered equilibrium decagonal Al-Pd-Mn quasicrystal overlayer on the 5-fold symmetric surface of an icosahedral Al-Pd-Mn monograin.

, 1989 There are several incentives to identify the analogues of dislocations and disclinations in quasicrystals. Penrose patterns are two-dimensional systems, and according to phase space counting fluctuations of the atomic displacements are so strong that exact long-range order is reduced to quasi-longrange order just as in periodic crystals.

Growth Modes of Quasicrystals [PDF]
Physical Review Letters, 2014 The growth of quasicrystals, i.e., aperiodic structures with long-range order, seeded from the melt is investigated using a dynamical phase field crystal model. Depending on the thermodynamic conditions, two different growth modes are detected, namely defect-free growth of the stable quasicrystal and a mode dominated by phasonic flips which are ...

Asymptotic estimates of large gaps between directions in certain planar quasicrystals
Journal of the London Mathematical Society, Volume 111, Issue 6, June 2025.Abstract For quasicrystals of cut‐and‐project type in Rd$\mathbb {R}^d$, it was proved by Marklof and Strömbergsson [Int. Math. Res. Not. IMRN (2015), no. 15, 6588–6617; erratum, ibid. 2020] that the limit local statistical properties of the directions to the points in the set are described by certain SLd(R)$\operatorname{SL}_d(\mathbb {R})$‐invariant ...

Aperiodically ordered nano-graphene on the quasicrystalline substrate
New Journal of Physics, 2020 Designing exotic structures in low dimensions is key in today’s quest to tailor novel quantum states in materials with unique symmetries. Particularly intriguing materials in this regard are low dimensional aperiodic structures with non-conventional ...

Tight-binding models in a quasiperiodic optical lattice
, 2014 This paper describes how one can use four standing wave laser fields to realize a two dimensional optical quasicrystal with eight-fold symmetry, closely related to the well-known octagonal or Ammann-Beenker tiling quasicrystal.

Comptes Rendus. Physique, 2014 The remarkable surface properties of quasicrystals have motivated extensive investigations of their intrinsic atomic and electronic structures. In this article, we summarize some of the main conclusions obtained so far. We also describe adsorption experiments where quasiperiodic surfaces are used as templates to grow thin films with novel structures ...

Use of Frit‐Disc Crucible Sets to Make Solution Growth More Quantitative and Versatile
Zeitschrift für anorganische und allgemeine Chemie, Volume 651, Issue 7, May 12, 2025.The recent availability of step‐edge, frit‐disc crucible sets (generally sold as Canfield Crucible Sets or CCS) has led to multiple innovations associated with the group's use of solution growth. The use of CCS allows for the clean separation of liquid from solid phases during the growth process.

In situ TEM study of precipitation in a quasicrystal-strengthened AL-alloy
Archives of Metallurgy and Materials, 2017 Precipitation kinetics and mechanisms within an Al-Mn-Be-Cu quasicrystal strengthened alloy at 300°C were studied using in-situ transmission electron microscopy. The alloy was cast into a copper mould.

Emergent Quasicrystalline Symmetry in Light-Induced Quantum Phase Transitions
, 2019 The discovery of quasicrystals with crystallographically forbidden rotational symmetries has changed the notion of the ordering in materials, yet little is known about the dynamical emergence of such exotic forms of order.
