Quasi One-Dimensional Charge-Density-Waves at Low Temperatures
Abstract
Description
Dynamic and static properties of the classical Fukuyama-Lee-Rice model and the renormalization and phase diagrams of a related quantum model with phase-slips are studied.
In the first part, the phase correlation function is calculated in the weak pinning limit by an one-loop renormalization group calculation and exactly in the strong pinning case. Further, the creep dynamics of these quasi-one-dimensional systems is studied by analytical and numerical approaches.
In the second part, the phase diagrams of the quantum model is studied by an anisotropic, finite-temperature renormalization group calculation.
