Chiral 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 کاملCharge density waves and the replica method
In this note I will present some analytic studies of the properties of charge density waves near the depinning point. Computations using the replica method are done in a simplified
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...
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 کاملHolographic Model at Finite Temperature with R-charge density
We consider a holographic model of QCD at finite temperature with nonzero chemical potentials conjugate to R-charge densities. A critical surface of the confinement-deconfinement phase transition is shown for five-dimensional charged black hole solution given by Behrnd, Cvetič and Sabra. On a special section of the parameter space, we find an critical curve being similar to the one expected in ...
