Quantum Quench Dynamics in the bond-alternating Heisenberg Model — •Mirco Marahrens — University of Stuttgart, Institute for Functional Matter and Quantum Technologies

We studying the bond-alternating Heisenberg model regarding its quench dynamics between different symmetry protected topological phases, namely the odd and even degenerated Haldane phases, and quenches to the trivial phase. Therefore we are using the Density Matrix Renormalization Group in the formalism of uniform matrix product states and a time evolution scheme purely based on matrix product operators constructed by finite state machines.
