相对论物质快速动力学模拟器
Fast kinetic simulator for relativistic matter
摘要:
我们提出了一个新的家庭的相对论晶格动力学计划的有效模拟强相互作用(流体)和弱相互作用(稀薄气体)制度的相对论流动。该方法也可以处理无质量和有质量的粒子,从而涵盖了极端相对论和温和相对论的制度一样。详细讨论了该方法在模拟上述区域的相对论性流场时的计算性能,并展望了该方法在夸克-胶子等离子体、石墨烯电子流和天体物理系统中的应用前景。
英文摘要:
We present a new family of relativistic lattice kinetic schemes for the efficient simulation of relativistic flows in both strongly-interacting (fluid) and weakly-interacting (rarefied gas) regimes. The method can also deal with both massless and massive particles, thereby encompassing ultra-relativistic and mildly-relativistic regimes alike. The computational performance of the method for the simulation of relativistic flows across the aforementioned regimes is discussed in detail, along with prospects of future applications for Quark-Gluon Plasma, electron flows in graphene and systems in astrophysical contexts.
