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.83 pages, 43 figures; diploma thesis (June 2001), in german with english summaryStrongly Correlated Electronstext
