From the large-scale structure of the universe to exotic states in nuclear matter: random or disordered spatial structures appear on nearly all length scales in very different physical, chemical, or biological systems. In systems with complex structu

This work investigates a chiral nucleon-meson model which is suited to analyze chiral symmetry breaking and the thermodynamics of nuclear matter at the same time. We go beyond the mean-field approximation by including pionic fluctuations in a non-per

Auf Grund von magnetischer Katalyse verst��rkt ein magnetisches Feld das chirale Kondensat, wodurch erwartet werden kann, dass auch die Vakuummasse der Nukleonen erh��ht wird. In dieser Arbeit wird gezeigt, dass es m��glich ist, magnetisc

The equation of state of nuclear matter is calculated at finite temperature in the framework of in-medium chiral perturbation theory up to three-loop order. The dependence of its thermodynamic properties on the isospin-asymmetry is investigated. The

In dieser Arbeit wird die Produktion leichter Mesonen und baryonischer Resonanzen in p+Nb Kollisionen bei E=3.5 GeV über die Rekonstruktion ihrer e+e- Zerfälle untersucht. Das Reaktionssystem erlaubt insbesondere die Produktion von Vektormesonen in

The subject of the present thesis is at first the investigation of model independent properties of the nucleon-nucleon (NN) interaction in the vacuum concerning the relativistic structure and the implications for nuclear matter properties. Relativist

The goal of this work is to draw a connection from the nuclear many-body problem to the fundamental theory of the strong interaction, quantum chromodynamics. Chiral perturbation theory, which is based on the symmetries and symmetry breaking patterns

The Hartree-Fock-Bogoliubov (HFB) theory, a well-known method used in non-relativistic nuclear physics, has been applied in the framework of a relativistic quantum field theory. It allows to treat the particle-hole and the particle-particle channel o

The EOS of nuclear matter is studied in the framework of relativistic density dependent hadron field theory (DDRH) and results are compared to the results of the phenomenological density dependent approach DD-ME1 which is devised to fit the propertie

In dieser Arbeit wird die quasifreie Photoproduktion von Pionenpaaren an gebundenen Nukleonengamma + Alpha → pi pi (Alpha-1) + Ny für die Festkörpertargets Kohlenstoff, Kalzium und Blei untersucht. Diese Messungen erlauben eine vom Isospin abhän
