Quasicrystals and Other Aperiodic Structures in Mineralogy

Crystals, 2016
In this article, we first present and discuss eighteenth-century descriptions of minerals that contributed decisively to the development of crystallography.

Electronic Structure Of Quasicrystals [PDF]

, 1998
The study of the electronic structure of quasicrystals is still a matter of investigations to date. The paper will report several significant experimental results obtained through spectroscopic techniques which involve the bulk material as well as the ...

Homogeneous holographic viscoelastic models and quasicrystals

Physical Review Research, 2020
We show that the field theories dual to the homogeneous holographic models with spontaneously broken translations display several distinctive properties of quasicrystals, aperiodic crystals with long-range order (e.g., incommensurate charge density waves)

Generic mobility edges in a class of non-Hermitian quasicrystals

Results in Physics
We present approximate solutions for the mobility edge (ME) in a specific class of one-dimensional non-Hermitian (NH) quasicrystals delineating between localized and extended states.

Quasicrystals [PDF]

, 1999
Created by Dr.Steffen Weber, the Quasicrystals Web site provides an introduction to this relatively new field of crystallography. Although much of the site is highly technical, those interested in related subjects will find exploring the thorough ...

Icosahedral quasicrystals by optical interference holography [PDF]

, 2006
Optical interference holography has been proven to be a useful technique in fabricating periodic photonic crystals in which electromagnetic waves are forbidden in certain frequency band gaps.

Image Sampling with Quasicrystals

Symmetry, Integrability and Geometry: Methods and Applications, 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.

Quasicrystals fabricated by holographic lithography [PDF]

, 2006
In this paper, we report the use of combining holography and photo-induced polymerization techniques to fabricate 2D mesoscale Penrose quasicrystals using 5 coherent beams. The effects of exposure dosage and polarizations of laser beams on the structures
