Abstract
This thesis advances and applies matrix product state (MPS) based algorithms to the solution of dynamical meanfield theory (DMFT) and its variants. The advances enable to solve quantum manybody problems in and out of equilibrium that were previously out of reach for any numerical treatment. In equilibrium, this concerns in particular the computation of the electronic  such as insulating, metallic, spinfreezed and many other  phases of highly complex realistic models for correlated materials. In nonequilibrium, this concerns in particular the understanding of the fundamental mechanisms of the relaxation behavior of quantum manybody systems on short and intermediate time scales.
