Stripe Liquid, Crystal, and Glass Phases of Doped Antiferromagnets

Abstract

A largely descriptive survey is given of the ordered phases of doped antiferromagnets, and of the long wavelength properties that can be derived from an order-parameter theory. In particular, we show that the competition between the long-range Coulomb repulsion and the strong short-distance tendency of doped holes to coalesce into regions of supressed antiferromagnetism leads to a variety of self-organized charge structures on intermediate length scales, of which ``stripes'' are the most common, both theoretically and experimentally. These structures lead to a rich assortment of novel electronic phases and crossover phenomena, as indicated in the title. We use the high temperature superconductors as the experimentally best-studied examples of doped antiferromagnets.
