Correlations and Area Laws in Open quantum Systems — •Michael Kastoryano and Jens Eisert — Freie Universität Berlin, Germany

Understanding the dynamic and static properties of correlated quantum systems on a lattice remains one of the important goals of condensed matter physics. We present here a deep connection between the relaxation behavior of Markovian open system dynamics and the correlation properties of the stationary state of the system, using methods from quantum information theory. As a consequence, we identify a regime where an Area Law can be shown to hold for all dimensions, and where the dynamics are stable to small perturbations. We conclude with a discussion of the implications of these results for the classical simulation of open quantum systems with matrix-product operators and the robust dissipative preparation of topologically ordered states of lattice spin systems.
