摘要

利用爱因斯坦-麦克斯韦-迪拉顿（EMD）模型，结合晶格量子色动力学（QCD）的状态方程和重子数易感信息，研究了 Nf=0、Nf=2 和 Nf=2+1 系统中的全息施温格效应。研究发现，临界电场在 Nf=0 时最小，这表明与 Nf=2 和 Nf=2+1 的系统相比，施温格效应更有可能发生。在所有体系中，临界电场随着化学势和温度的增加而减小。此外，化学势分析证实，最大总化学势能随化学味数量的增加而增加，这表明现有粒子可能会降低粒子对产生的概率。美国物理学会出版 2025

Holographic Schwinger effect in flavor-dependent systems

The holographic Schwinger effect is investigated in systems with Nf=0, Nf=2, and Nf=2+1 using the Einstein-Maxwell-dilaton (EMD) model, incorporating equation of state and baryon number susceptibility information from lattice quantum chromodynamics (QCD). It is found that the critical electric field is smallest for Nf=0, indicating that the Schwinger effect is more likely to occur than in systems with Nf=2 and Nf=2+1. The critical electric field decreases with increasing chemical potential and temperature across all systems. Additionally, potential analysis confirms that the maximum total potential energy increases with the number of flavors, suggesting that existing particles may reduce the probability of particle pair production.
