Induced Luttinger Liquid Behavior in an Exactly Solvable Model of Stripes
arXiv:cond-mat/9903189
Abstract
We study an exactly solvable model describing a stripe consisting of a Toda array of anharmonic elastic chains sandwiched between two conducting chains. It is shown that the presence of a charge on one chain generates a gapless excitation branch (Luttinger liquid) on the other and leads to increase in the phonon frequencies.
