Beim Aufsuchen von Lösungen kann man einmal von erweiterten Lösungen der statischen Modelle ausgehen, zum anderen läßt sich der ungefähre Verlauf der elektromagnetischen Feldstärken in größerer Entfernung von einer rotierenden Ladungsverteilung aus klassischen...
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 کاملSelf-assembly and electrostriction of arrays and chains of hopfion particles in chiral liquid crystals
Some of the most exotic condensed matter phases, such as twist grain boundary and blue phases in liquid crystals and Abrikosov phases in superconductors, contain arrays of topological defects in their ground state. Comprised of a triangular lattice of double-twist tubes of magnetization, the so-called 'A-phase' in chiral magnets is an example of a thermodynamically stable phase with topological...
متن کاملTuning structural and mechanical properties of two-dimensional molecular crystals: the roles of carbon side chains.
A key requirement for the future applicability of molecular electronics devices is a resilience of their properties to mechanical deformation. At present, however, there is no fundamental understanding of the origins of mechanical properties of molecular films. Here we use quinacridone, which possesses flexible carbon side chains, as a model molecular system to address this issue. Eight molecul...
