Copernican Crystallography [PDF]

open access: yesPhys.Rev.Lett.68:1172-1175,1992, 1991
Redundancies are pointed out in the widely used extension of the crystallographic concept of Bravais class to quasiperiodic materials. Such pitfalls can be avoided by abandoning the obsolete paradigm that bases ordinary crystallography on microscopic periodicity.

Cosmic Crystallography with a Pullback [PDF]

open access: yesPhys.Lett. A261 (1999) 235-239, 1999
We present a modified version of the cosmic crystallography method, especially useful for testing closed models of negative spatial curvature. The images of clusters of galaxies in simulated catalogs are ``pulled back'' to the fundamental domain before ...

Megahertz serial crystallography [PDF]

open access: yesNature Communications, 2018
AbstractThe new European X-ray Free-Electron Laser is the first X-ray free-electron laser capable of delivering X-ray pulses with a megahertz inter-pulse spacing, more than four orders of magnitude higher than previously possible. However, to date, it has been unclear whether it would indeed be possible to measure high-quality diffraction data at ...

Cohomology for Anyone [PDF]

open access: yes, 2003
Crystallography has proven a rich source of ideas over several centuries. Among the many ways of looking at space groups, N. David Mermin has pioneered the Fourier-space approach.

Combinatorial problems of (quasi-)crystallography [PDF]

open access: yesIn: Quasicrystals - Structure and Physical Properties, ed. H.-R. Trebin (Wiley-VCH, Weinheim, 2003), pp. 160-171, 2002
Several combinatorial problems of (quasi-)crystallography are reviewed with special emphasis on a unified approach, valid for both crystals and quasicrystals. In particular, we consider planar sublattices, similarity sublattices, coincidence sublattices,

The Crystallography of Color Superconductivity [PDF]

open access: yesPhysical Review D, 2002
We develop the Ginzburg-Landau approach to comparing different possible crystal structures for the crystalline color superconducting phase of QCD, the QCD incarnation of the Larkin-Ovchinnikov-Fulde-Ferrell phase.

Crystallography on Curved Surfaces [PDF]

open access: yesProceedings of the National Academy of Sciences, 2006
We study static and dynamical properties that distinguish two dimensional crystals constrained to lie on a curved substrate from their flat space counterparts.

Electron crystallography [PDF]

open access: yesIUCrJ, 2019
A Special Issue on the topic of Electron Crystallography, now available in the August 2019 issue of Acta Crystallographica, Section B, contains contributions which we hope will interest readers of IUCrJ.
