Unitary perturbation theory approach to real-time evolution problems
A. Hackl, S. Kehrein
We discuss a new analytical approach to real-time evolution in quantum many-body systems. Our approach extends the framework of continuous unitary transformations such that it amou…

Density matrix renormalization group study of a quantum impurity model with Landau-Zener time-dependent Hamiltonian
Cheng Guo, Andreas Weichselbaum, Stefan Kehrein +2
We use the adaptive time-dependent density matrix renormalization group method (t-DMRG) to study the nonequilibrium dynamics of a benchmark quantum impurity system which has a time…

Interaction Quench in the Hubbard model
M. Moeckel, S. Kehrein
Motivated by recent experiments in ultracold atomic gases that explore the nonequilibrium dynamics of interacting quantum many-body systems, we investigate the opposite limit of La…
