Phys. Rev. B 78, 195119 (2008) [12 pages]Electron and phonon correlations in systems of one-dimensional electrons coupled to phononsReceived 16 August 2008; revised 11 October 2008; published 19 November 2008 Electron and phonon correlations in systems of one-dimensional electrons coupled to phonons are studied at low temperatures by emphasizing on the effect of electron-phonon backward scattering. It is found that the 2kF-wave components of the electron density and phonon displacement field share the same correlations. Both correlations are quasi-long-ranged for a single conducting chain coupled to one-dimensional or three-dimensional phonons, and they are long-ranged for repulsive electron-electron interactions for a three-dimensional array of parallel one-dimensional conducting chains coupled to three-dimensional phonons. © 2008 The American Physical Society URL:
