量子纠缠能否在子系统的纠缠熵已经饱和后继续增长?我们利用真正的多体纠缠熵(genuine multi-entropy)来探讨这一问题,该量探测超越两体纠缠的多体纠缠结构。在双侧BTZ黑洞中,当固定三分割的每个子系统熵都已饱和后,该量随时间线性增长,从而延长了纠缠探测爱因斯坦-罗森桥增长的区间。这一结果通过识别普通纠缠熵无法看见的多体结构,精炼了ER=EPR关系。一些自旋链模型和空间分割的Sachdev-Ye-Kitaev(SYK)模型表现出不同的瞬态行为,而全息、SYK模型和Haar随机态中的晚期平台值则展现出普适行为。
英文摘要
Can quantum entanglement continue to grow even after the entanglement entropies of subsystems have saturated? We address this question using genuine multi-entropy, which probes multi-partite entanglement structure beyond bipartite entanglement. In a two-sided BTZ black hole, this quantity grows linearly with time after every subsystem entropy of a fixed tripartition has saturated, extending the interval in which entanglement detects Einstein-Rosen bridge growth. The result refines the ER=EPR relation by identifying multi-partite structure invisible to ordinary entanglement entropies. Some spin-chain models and the spatially partitioned Sachdev-Ye-Kitaev (SYK) model exhibit distinct transients, while the late-time plateau values in holography, the SYK model, and Haar-random states share a universal behaviour.
