AI总结:

该研究用张量网络模拟有质量 Schwinger 模型中的双喷注,揭示强–弱耦合转变附近涌现的无电荷有效流体及其与空间纠缠熵的关联。

摘要:

我们分析了有质量 Schwinger 模型中两个光速喷注所产生的能量、动量与空间纠缠之间的关联。利用张量网络方法,我们表明:对于 m/g > 1/π,在强耦合到弱耦合转变附近,中心快度区域出现近乎完美且无电荷的有效流体行为,并具有普适的能量–压强关系。能量和压强的演化与空间纠缠熵的上升密切相关,表明量子动力学发挥关键作用。其中部分观测结果可用于分析当前对撞机能量下的高多重数喷注碎裂事件,以及能量–能量和能量–电荷关联子。

英文摘要:

We analyze the correlation between the energy, momentum and spatial entanglement produced by two luminal jets in the massive Schwinger model. Using tensor network methods, we show that for m/g > 1/π, in the vicinity of the strong to weak coupling transition, a nearly perfect and chargeless effective fluid behavior appears around the mid-rapidity region with a universal energy-pressure relationship. The evolution of energy and pressure is strongly correlated with the rise of the spatial entanglement entropy, indicating a key role of quantum dynamics. Some of these observations may be used to analyze high multiplicity jet fragmentation events, energy-energy and energy-charge correlators at current collider energies.
