Abstract:
In this work a method is presented, which allows one to calculate the phase diagram of the Bose-Hubbard model for arbitrary dimension and filling factors via Kato's formulation of the perturbation series. This formulation enables a diagrammatical ansatz, which acribes the calculation of observables to the generation and analysis of diagrams. Within this diploma thesis several types of diagrams necessary to calculate the phase diagram and correlation functions were generated.
