چکیده

Inspired by the cuprate stripes, we consider the problem of a one-dimensional metal living on a delocalized trajectory in two dimensional space: the metallic lattice string. A model is constructed with maximal coupling between longitudinal and transversal charge motions, which nevertheless renormalizes into a minimal generalization of the Luttinger liquid: an independent set of string modes has to be added to the long-wavelength theory, with a dynamics governed by the quantum sine-Gordon model. @S0163-1829~98!51742-0#

Mean-field description of the phase string effect in the t-J model

A mean-field treatment of the phase string effect in the t-J model is presented. Such a theory is able to unite the antiferromagnetic ~AF! phase at half-filling and the metallic phase at finite doping within a single theoretical framework. We find that the low-temperature occurrence of the AF long-range ordering ~AFLRO! at half-filling and superconducting condensation in the metallic phase are ...

Spin-gap proximity effect mechanism of high-temperature superconductivity

When holes are doped into an antiferromagnetic insulator they form a slowly fluctuating array of ‘‘topological defects’’ ~metallic stripes! in which the motion of the holes exhibits a self-organized quasi-onedimensional electronic character. The accompanying lateral confinement of the intervening Mott-insulating regions induces a spin gap or pseudogap in the environment of the stripes. We prese...

Anisotropic electromagnetic response of lightly doped La2-xSrxCuO4 within the CuO2 planes.

Using infrared spectroscopy, we show that spin self-organization in untwinned La2-xSrxCuO4 (LSCO) crystals has profound consequences for the dynamical conductivity sigma(omega). The electronic response of CuO2 planes acquires significant anisotropy in the spin ordered state with enhancement of the conductivity along the direction of the diagonal spin stripes by up to a factor of 2. An examinati...

Infrared and Raman Studies of Charge Ordering in Organic Conductors, BEDT-TTF Salts with Quarter-Filled Bands

This paper reviews charge ordering in the organic conductors, β′′-(BEDT-TTF) (TCNQ), θ-(BEDT-TTF)2X, and α-(BEDT-TTF)2X. Here, BEDT-TTF and TCNQ represent bis(ethylenedithio)tetrathiafulvalene and 7,7,8,8-tetracyanoquinodimethane, respectively. These compounds, all of which have a quarter-filled band, were evaluated using infrared and Raman spectroscopy in addition to optical conductivity measu...

Spin Conductivity and Spin-Charge Separation in the High Tc Cuprates

We study both the spin and electrical conductivities in models of relevance to the high Tc cuprates. These models describe metallic states with or without spin-charge separation. We demonstrate that, given a linear in temperature dependence of the electrical resistivity, the spin resistivity should also be linear in temperature in the absence of spin-charge separation and under conditions appro...
