Zusammenfassung:	Göttingen, Univ., Diss., 2013 In this thesis, antiferromagnetic and superconducting order in the Kondo-lattice model is investigated by means of the dynamical mean-field theory (DMFT) in combination with the numerical renormalization group (NRG) method. First, these numerical methods are introduced and a special emphasis is put on the inclusion of superconducting order by employing the Nambu formalism. In the next chapter, the Kondo-lattice model as a paradigmatic model for heavy-fermion system is introduced. The analysis of the paramagnetic state at zero temperature reviews the description of the electronic system as a...
