Computational Design and Thermodynamic Stability of Aperiodic Crystals and their Approximants
Aperiodic crystals are crystalline structures that lack periodicity (e.g. quasicrystals). These structures revolutionized the field of crystallography just a few years back.

Experimental signatures of spicy local density of states in quasicrystals [PDF]
, 2009 Our recent investigations on the valence electronic structure of the icosahedral Al70Pd21Mn9 quasicrystals by means of scanning tunneling microscopy and spectroscopy at low temperatures (5 K) have revealed signatures of a spiky local density of states ...

STUDIES ON APERIODIC CRYSTALS IN Al-Mn AND Al-V ALLOYS BY MEANS OF TRANSMISSION ELECTRON MICROSCOPY
, 1986 Electron microscopy has been used to study quasicrystals and T phase in rapidly cooled Al-14at%Mn and Al-16at%V. The T phase can also be produced by interdiffusion in evaporated Al/Mn layers.

The aperiodic nature of incommensurately modulated structures [PDF]
, 2018 The discovery of aperiodic crystals is perhaps one of the most important event which has changed our vision on crystalline architectures since the discovery of diffraction 100years ago. It was the merit of a Dutch crystallographer, P.M.

Two-dimensional photonic quasicrystals by single beam computer-generated holography [PDF]
, 2008 Recently important efforts have been dedicated to the realization of a new kind of photonic crystals, known as photonic quasicrystals, in which the lack of the translational symmetry is compensated by rotational symmetries not achievable by the ...

Electronic and magnetic properties of Tsai quasicrystals and their approximants under pressure
, 2022 Quasicrystals constitute a special category of crystals exhibiting long-range order without periodicity. This strange feature allows them to exhibit rotational symmetries prohibited in regular crystals, such as 5-, 8-, 10- or 12-fold symmetry.

Topology of the phase in aperiodic crystals
, 1990 The phase degrees of freedom of aperiodic crystals (quasicrystals) are far from being understood. In this paper we study in great detail the geometrical and topological properties of the « phase space » of quasicrystals, for usual quasicrystalline ...
