Tensor Network Techniques and Dynamical Systems — Nicola Pancotti¹, Michael Knapp², David Huse³, Mari Carmen Banuls¹, and •Ignacio Cirac¹ — ¹Max-Planck Institut für Quantenoptic, Garching, Germany — ²Technical University of Munich, Garching, Germany — ³University of Princeton, Princeton, US

Tensor networks can be used to efficiently describe the equilibrium properties of many-body quantum systems with local interactions. However, they fail to describe their dynamics, at least for long times. In this talk we will present several methods based on tensor networks to extract dynamical properties of one dimensional spin chains. In particular, we will show how one can construct matrix product operators that quasi commute with the system Hamiltonian, and how this is related to the thermalization process.
