Title: Charge density waves in disordered media circumventing the Imry-Ma argument

Abstract

Two powerful theoretical predictions, Anderson localization and the Imry-Ma argument, impose significant restrictions on the phases of matter that can exist in the presence of even the smallest amount of disorder in one-dimensional systems. These predictions forbid electrically conducting states and ordered states respectively. It was thus remarkable that a mechanism to circumvent Anderson localization relying on the presence of correlated disorder was found, that is also realized in certain biomolecular systems. Here, in a similar manner, we show that the Imry-Ma argument can be circumvented, resulting in the formation of stable ordered states with discrete broken symmetries in disordered one dimensional systems. We then investigate other mechanisms by which disorder can destroy an ordered state.

  • The low-temperature phase of a model of pinned, two-dimensional flux lines is analytically shown to be glassy. Typical energy barriers {ital L} diverge as (ln{ital L}){sup 1/2} as the length scale {ital L}{r arrow}{infinity}. This implies a voltage-current relation of the form {ital V}={ital C}{sub 1}{ital I} exp{l brace}{minus}{ital C}{sub 2}(ln({ital I}{sub 0}/{ital I})){sup 1/2}. The growth velocity {ital V}{sub {ital G}} of the surface of a disordered crystal is given by {ital V}{sub {ital G}}={ital c}{sub 3}{Delta}{mu} exp{l brace}{minus}{ital C}{sub 4}(ln({Delta}{mu}{sub {ital c}}/{Delta}{mu})){sup 1/2}{r brace}, where {Delta}{mu} is the crystal-liquid chemical-potential difference. Similar results hold for 2D charge-density waves,more » if dislocations in the charge-density wave are ignored.« less
  • When averaged over sources or disorder, cross correlation of diffuse fields yields the Green's function between two passive sensors. This technique is applied to elastic ultrasonic waves in an open scattering slab mimicking seismic waves in the Earth's crust. It appears that the Rayleigh wave reconstruction depends on the scattering properties of the elastic slab. Special attention is paid to the specific role of bulk to Rayleigh wave coupling, which may result in unexpected phenomena, such as a persistent time asymmetry in the diffuse regime.
  • We study self-avoiding random walks in an environment where sites are excluded randomly, in two and three dimensions. For a single polymer chain, we study the statistics of the time averaged monomer density and show that these are well described by multifractal statistics. This is true even far from the percolation transition of the disordered medium. We investigate solutions of chains in a disordered environment and show that the statistics cease to be multifractal beyond the screening length of the solution.
