Interesting discoveries have recently been made in the area of solid state physics and nano technology regarding electronic systems that are confined to reduced spatial dimensions. Under these circumstances the quantum nature of the electrons begins

The prediction and the experimental discovery of topological insulators has set the stage for a novel type of electronic devices. In contrast to conventional metals or semiconductors, this new class of materials exhibits peculiar transport properties

We study the dynamics in low dimensional correlated quantum systems. Advances in this thesis are three-fold. First, as a methodical point we extend the real-time formulation of the functional renormalization group approach introduced in [1]. Describi

We investigate the phenomenon of spin and charge fractionalization of an electron injected into a strongly correlated chain, namely the 1D t-J model, by means of the time-dependent DMRG method. In order to compare and interpret our results we use the

In this thesis ground state properties of S = 1 spin chains with exchange and single-ion anisotropy are analysed. Following earlier publications two cases are mainly considered: A fixed ratio of the two anisotropies as well as a fixed and strong exch

In this thesis, we study the properties of excitations in the systems of interacting fermions. These excitations can be bosonic such as collective modes which we handle in the first part of this thesis or fermionic like quasi particles and quasi hole

With this thesis we provide a thorough examination of the electronic and transport properties of interacting metallic single-walled carbon nanotubes (SWNTs) in the low energy regime, corresponding to excitation energies in the range of about 1 eV aro

Single-wall carbon nanotubes (SWCNTs) are a fascinating material because they exhibit many outstanding properties. Due to their unique geometric structure, they are a paradigm for one-dimensional systems. Furthermore, depending on their chirality, th
