1. Strongly Correlated Models in One Dimension from a Density Matrix Renormalization Group Perspective
Sammanfattning : The density matrix renormalization group (DMRG) is a numerical method for studying low dimensional strongly correlated models. The study of these models is one of the most active areas of condensed matter physics today and has been spurred not only by the discovery of high temperature superconductivity but also by experiments on new compounds.

4. Numerical Renormalization, Doped Antiferromagnets, and Statistics - Topics in Low Dimensional Physics
Sammanfattning : The first part of the thesis deals with so called numerical renormalization group methods, and in particular the density-matrix renormalization group (DMRG). This method performs extremely well for large one-dimensional quantum systems like spin-chains and Hubbard models. LÄS MER
