Atomic nanowires formed by self-assembled growth on semiconducting surfaces represent a feasible physical realization of quasi-1D electron systems and can be used to study fascinating 1D quantum phenomena. The system in the focus of this thesis, Si(5

In this thesis a method for deriving effective models for one-dimensional spin systems is introduced. It is based on matrix product state (MPS) and exploits translation invariance to efficiently work in the thermodynamic limit. It is tested on two an

The field of low-dimensional magnetism is one of the most active research areas in condensed matter physics. Low dimensional quantum magnets provide unique possibilities to study ground and excited states of quantum models, to explore new phases of m

Within the last decades low-dimensional frustrated quantum spin systems have attracted great interest in the field of modern research. In these systems a competition of various magnetic interactions takes place, leading to an energetically degenerate

Das Ziel dieser Arbeit war die Entwicklung eines wissenschaftlichen Codes, der in der Lage ist realit��tsnahe Systeme zu simulieren, und diesen auf einen, nicht gut verstandenen, experimentellen Effekt anzuwenden. Dieser experimentell bekannte Ef
