Classification of charge density waves based on their nature.
The concept of a charge density wave (CDW) permeates much of condensed matter physics and chemistry. CDWs have their origin rooted in the instability of a one-dimensional system described by Peierls. The extension of this concept to reduced dimensional systems has led to the concept of Fermi surface nesting (FSN), which dictates the wave vector [Formula: see text] of the CDW and the correspondi...
متن کاملChiral charge-density waves.
We discovered the chirality of charge-density waves (CDW) in 1T-TiSe₂ by using STM and time-domain optical polarimetry. We found that the CDW intensity becomes Ia₁∶Ia₂∶Ia₃ = 1∶0.7 ± 0.1∶0.5 ± 0.1, where Ia(i) (i=1,2,3) is the amplitude of the tunneling current contributed by the CDWs. There were two states, in which the three intensity peaks of the CDW decrease clockwise and anticlockwise. The ...
متن کاملOn Transversely Driven Charge-Density Waves
By means of a microscopic theory we calculate the effect of a current flowing transverse to conducting chains on the charge-density wave (CDW) dynamics along the chains. In contrast to a recent prediction (L. Radzihovsky and J. Toner, Phys. Rev. Lett. 81, 3711 (1998)) we found that contributions from transverse flows of electron-like and hole-like quasiparticles to the force exhibited by the CD...

متن کاملCoulombian disorder in Charge Density Waves
When unscreened charged impurities are introduced in charge density wave system the long wavelength component of the disorder is long ranged and dominates static correlation functions. We calculate the x-ray intensity and find that it is identical to the one produced by thermal fluctuations in a disorder-free smectic-A. We suggest that this effect could be observed in the blue bronze material K...
