摘要:

利用引力/规范对应,我们构造了一个全息模型,用来模拟零密度下的格点量子色动力学物态方程,研究物态方程对温度和重子化学势的依赖性.我们还得到了在临界点和穿过模型预测的一级跃迁线时,由重夸克拖曳力、朗之万扩散系数和喷注猝灭参数表示的热稠密等离子体中轻重部分子的能量损失。

英文摘要:

By using gravity/gauge correspondence, we construct a holographic model, constrained to mimic the lattice QCD equation of state at zero density, to investigate the temperature and baryon chemical potential dependence of the equation of state. We also obtained the energy loss of light and heavy partons within the hot and dense plasma represented by the heavy quark drag force, Langevin diffusion coefficients and jet quenching parameter at the critical point and across the first-order transition line predicted by the model.
