论文摘要
我们研究了夸克 - 胶状等离子体中非亚伯电荷（颜色 - 单词和八位字）的Quarkonia的Lindbladian量子机械演化的性质。我们确认，在lindblad方程中的重夸克后坐力正确地将Quarkonium彩色状态在模拟方法中的统计误差中得到热量。我们还证明，偶极极限中的Lindblad方程可以提供有效的替代方法，该方法适用于在热化之前的有限时间演化，并大大降低了数值成本。我们的发现将成为对相对论重型离子碰撞中Quarkonium Dynamics大规模模拟的基础。
We study the properties of the Lindbladian quantum mechanical evolution of quarkonia with non-Abelian charges (color-singlet and octet) in the quark-gluon plasma. We confirm that heavy quark recoils in the Lindblad equation correctly thermalize quarkonium colorful states within statistical errors from the simulation method. We also demonstrate that the Lindblad equation in the dipole limit can provide an efficient alternative method, which is applicable to a finite time evolution before thermalization and dramatically reduces the numerical cost. Our findings will serve as a foundation for large-scale simulation of quarkonium dynamics in the relativistic heavy-ion collisions.
