摘要:
我们研究了新引入的 AMY QCD 动力学理论部分子级联 ALPACA 中的热化与各向同性化过程。对于热化,我们考虑过占据初始条件的情况,并研究分布随时间演化弛豫到热平衡的过程。我们发现,与已知解析结果相比,系统如预期般热化。对于各向异性系统,我们初步研究了在具有周期性边界条件的均匀盒子中,类色玻璃凝聚体初始条件下各向同性化的定性行为。
英文摘要:
We look at thermalization and isotropization processes in the newly introduced AMY QCD kinetic theory parton cascade ALPACA. For thermalization, we consider the case of overoccupied initial conditions, and study the time evolution of the distribution as it relaxes to thermal equilibrium. We find that the system thermalizes as expected compared to known analytical results. For anisotropic systems, we take a first look at the qualitative behaviour of isotropization for Color Glass Condensate-like initial conditions in a homogeneous box with periodic boundary conditions.
