Development of Symmetry Concepts for Aperiodic Crystals
An overview is given of the use of symmetry considerations for aperiodic crystals. Superspace groups were introduced in the seventies for the description of incommensurate modulated phases with one modulation vector. Later, these groups were also used for quasi-periodic crystals of arbitrary rank. Further extensions use time reversal and time translation operations on magnetic and electrodynami...
متن کاملAperiodic crystals and superspace concepts.
For several decades the lattice periodicity of crystals, as shown by Laue, was considered to be their essential property. In the early sixties of the last century compounds were found which for many reasons should be called crystals, but were not lattice periodic. This opened the field of aperiodic crystals. An overview of this development is given. Many materials of this kind were found, somet...
متن کاملAperiodic Tilings: Breaking Translational Symmetry
Classical results on aperiodic tilings are rather complicated and not widely understood. Below an alternative approach to these results is offered in hope to provide additional intuition not apparent in classical works. 1 Palettes and Tilings Physical computing media are always asymmetric. Their symmetry is broken by irregularities, physical boundaries, external connections, etc. Such peculiari...
متن کاملColor Symmetry of Aperiodic Structures
The Fourier-space approach to crystal symmetry 1;2 is extended to colored quasiperiodic structures as an example of the general case of indistinguishable quasiperiodic multicomponent elds. Examples are given of 2-and 5-color space groups on the 10-fold 2-dimensional lattice. We consider a multicomponent quasiperiodic eld (r) whose components (r) could specify a tensor eld, as in magnetically or...
متن کاملTheory of Phasons in Aperiodic Crystals
The possibility of embedding a quasi-periodic structure into a higher-dimensional superspace gives rise to an interpretation of certain dynamical excitations as motions in the additional space. These excitations then are called phason excitations. There is always infinite degeneracy of the ground state of an aperiodic quasi-periodic system, but this degeneracy leads only to zero frequency modes...
