Multi-orbital Hubbard model is well known for its rich phase diagram, is commonly used for simulation at real materials. Dynamical susceptibilityis related to spectrum of collective excitations in solids. In this thesis we present a dynamical mean-fi

Die Quantenchromodynamik beschreibt das Verhalten von Quarks, den Bestandteilen der Nukleonen, und deren Wechselwirkung mit Gluonen, den Trägern der starken Kernkraft. Sie beschreibt, wie die Nukleonen gebildet und Atomkerne zusammengehalten werden.

In dieser Arbeit anlysieren wir den Einfluss von Dissipation auf Quantensysteme. Da man ein reales Quantensystem nie perfekt vor äußeren Einflüssen schützen kann, unterliegt jedes System der Dekohärenz. Diese kleine Kopplung mit der Umgebung kan

Für die Herleitung der Volumenformel einer dreiseitigen Pyramide verwendet man in der Regel das Modell eines oben offenen, prismenförmigen Hohlkörpers, dem man drei Teilpyramiden mit paarweise gleicher Grundfläche und Höhe entnehmen kann. Mit de

The focus of this thesis is the investigation of regular oscillator networks with numerical and analytical tools. Such systems are ubiquitous in nature and can emerge in the shape of vastly different processes. Among others, they can be mathematicall

Despite being considered as the correct theory for describing the interaction between gluons and quarks, Quantum Chromodynamics (``QCD'') still has elusive features which should be investigated. Although the theory can be dealt with at high energy by

Four-fermion theories are quantum field theories that describe interactions between fermions via a fourth power of the field in the Lagrangian. Formulated in three spacetime dimensions, their purpose is twofold. On the one hand, they serve as low-ene

In this thesis, quantum cluster methods are used to calculate electronic properties of correlated-electron systems. A special focus lies in the determination of the ground state properties of a 3/4 filled triangular lattice within the one-band Hubbar
