拓扑速度限制

Topological Speed Limit

Tan Van Vu, Keiji Saito

摘要:

任何物理系统都以有限的速度演化,这不仅受到能量成本的限制,而且还受到底层动力学的拓扑结构的限制。在这封信中,通过考虑这样的结构信息,我们得到一个统一的拓扑速度限制的物理状态的演化使用最佳的运输方法。我们证明了改变状态所需的最小时间是由离散Wasserstein距离和时间平均速度的下界,离散Wasserstein距离编码了系统的拓扑信息。得到的界是紧的,适用于广泛的动态,从确定性到随机,经典的量子系统。此外,该界限提供了深入了解达到最大速度的最佳过程的设计原则。我们展示了我们的结果的化学反应网络和相互作用的多体量子系统的应用。

英文摘要:

Any physical system evolves at a finite speed that is constrained not only by the energetic cost but also by the topological structure of the underlying dynamics. In this Letter, by considering such structural information, we derive a unified topological speed limit for the evolution of physical states using an optimal transport approach. We prove that the minimum time required for changing states is lower bounded by the discrete Wasserstein distance, which encodes the topological information of the system, and the time-averaged velocity. The bound obtained is tight and applicable to a wide range of dynamics, from deterministic to stochastic, and classical to quantum systems. In addition, the bound provides insight into the design principles of the optimal process that attains the maximum speed. We demonstrate the application of our results to chemical reaction networks and interacting many-body quantum systems.
