On quasi-locality and decay of correlations for long-range models of open quantum spin systems
Year: 2024
Type: article
Abstract: We consider models of open quantum spin systems with irreversible dynamics and show that general quasi-locality results for long-range models, e.g. as proven for the Heisenberg dynamics associated to quantum systems in Matsuta et al (2017 Ann. Henri Poincare 18 519–28), naturally extend to this setting. Given these bounds, we provide two applications. First, we use these results to obtain estimates on a strictly local approximation of these finite-volume, irreversible dynamics. Next, we show how these bounds can be used to estimate correlation decay in various states.
