Temperature Dependence of the Spectral Function through the Peierls Transition in Quasi-One-Dimensional Compounds a metal-insulator transition at 180 K is associated with a lattice distortion, the formation of a charge density wave and the opening of an energy gap... B Dardel,D Malterre,M Grioni...
Based on a model for quasi-one-dimensional organic polymer ferromagnets, the Peierls distortion in a conjugated carbon chain with side radicals, which contains unpaired electrons, is investigated. When the hopping mediated interaction between the main chain and the side radicals is greater than a ...
These results are consistent with the picture that the threefold coordination arises from a Peierls-type distortion from a sixfold-coordinated, simple-cubic-like structure. High-density and high-temperature properties are also studied, and it is shown that a crossover to a sixfold-coordinated ...
spin-Peierls transitionphotoinduced phase transitionoptical conductivityWe discuss photogenerated midgap states of a one-dimensional (1D) dimerized Mott insulator, potassium-tetracyanoquinodimethane (K-TCNQ). Two types of phonon modes are taken into account: intermolecular and intramolecular vibrations. We ...
Spin-Peierls transition in the Ge:As semiconductor impurity system in the vicinity of the insulator-metal phase transition The effect of an elastic spontaneous distortion of the crystal lattice of a doped semiconductor Ce:As was observed near the insulator-metal (IM) phase tran... AI Veinger,AG...
We study planar domains with exemplary boundary singularities of the form of cusps. A natural question is how much elastic energy is needed to flatten these cusps; that is, to remove singularities. We give, in a connection of quasidisks, a sharp integrability condition for the distortion functio...
