- W2982313648 abstract "In locally interacting quantum many-body systems, the velocity of information propagation is finitely bounded, and a linear light cone can be defined. Outside the light cone, the amount of information rapidly decays with distance. When systems have long-range interactions, it is highly nontrivial whether such a linear light cone exists. Herein, we consider generic long-range interacting systems with decaying interactions, such as R−α with distance R. We prove the existence of the linear light cone for α>2D+1 (D, the spatial dimension), where we obtain the Lieb-Robinson bound as ∥[Oi(t),Oj]∥≲t2D+1(R−v¯t)−α with v¯=O(1) for two arbitrary operators Oi and Oj separated by a distance R. Moreover, we provide an explicit quantum-state transfer protocol that achieves the above bound up to a constant coefficient and violates the linear light cone for α<2D+1. In the regime of α>2D+1, our result characterizes the best general constraints on the information spreading.Received 25 March 2020Revised 18 June 2020Accepted 19 June 2020DOI:https://doi.org/10.1103/PhysRevX.10.031010Published by the American Physical Society under the terms of the Creative Commons Attribution 4.0 International license.
