Quantum many-body systems far out of equilibrium can lead to rich physics and are challenging to understand due to the exponentially large Hilbert space. We employ large scale tensor network techniques in numerical simulations and investigate the dynamics of different model systems, where we focus on the dimensional crossover in two-dimensional systems and on many-body localization. Moreover, we introduce a new method to efficiently simulate the dynamics of mixed states using minimally entangled purified states. The developed codes are made available as an open-source library.
