Disclinations in quasicrystals.
نویسندگان
چکیده
The most significant feature in the transition from the quasicrystalline to the amorphous state is the loss of long-range bond-orientational order. Disclinations are candidates for elementary excitations which destroy angular correlations. Genera lizing the topological defect classification, we investigate point singularities in two-dimensional pentagonal quasicrystals and construct disclinations, dislocations, and disclination dipoles.

Elastic theory of icosahedral quasicrystals – application to straight dislocations
In quasicrystals, there are not only conventional, but also phason displacement fields and associated Burgers vectors. We have calculated approximate solutions for the elastic fields induced by two-, threeand fivefold straight screwand edge-dislocations in infinite icosahedral quasicrystals by means of a generalized perturbation method. Starting from the solution for elastic isotropy in phonon ...
متن کاملOrientational properties of nematic disclinations.
Topological defects play a pivotal role in the physics of liquid crystals and represent one of the most prominent and well studied aspects of mesophases. While in two-dimensional nematics, disclinations are traditionally treated as point-like objects, recent experimental studies on active nematics have suggested that half-strength disclinations might in fact possess a polar structure. In this a...
متن کاملRhombellanic Crystals and Quasicrystals
Design of some crystal and quasicrystal networks, based on rhombellane tiling,is presented. [1,1,1]Propellane,is a synthesized organic molecule; its hydrogenated form, the bicyclo[1.1.1]pentane,may be represented by the complete bipartite graph K2,3 which is the smallest rhombellane. Topology of translational and radial structures involving rhombellanes is described in terms of vertex symbol, c...
متن کاملUndulating paired disclinations (oily streaks) in lyotropic liquid crystals
2014 Optical microscopy reveals regular periodic undulations of the lateral position of the axes of paired disclinations or « oily streaks » in thin, fully hydrated lyotropic liquid crystals of dimyristoyl phosphatidylcholine (DMPC) in the L03B1 (smectic A) phase. These undulations explain the characteristic dark bands that traverse the paired disclinations on observation with crossed polarizer...
متن کاملCharge localization around disclinations in monolayer graphite
Using a continuum model, we obtain qualitative results that imply charge localization around negative curvature disclinations (i.e. rings with more than 6 Carbon atoms) in a graphite sheet. Conversely, it is found that positive curvature disclinations repel charge, independent of its sign.
