论文摘要
具有不同相互作用和粒子质量的三维相对论气体的分子动力学模拟。在所有情况下,速度分布都与Jüttner分布数字一致。我们展示了如何将相对论气体耦合到恒温器,以在给定的温度T下模拟规范集合。恒温器的行为是作为热惯性的函数研究的,其适当范围是通过评估动能波动来确定的。
Molecular dynamics simulations of a three dimensional relativistic gas with a soft potential are conducted with different interactions and particle masses. For all cases the velocity distribution agrees numerically with the Jüttner distribution. We show how the relativistic gas can be coupled to a thermostat to simulate the canonical ensemble at a given temperature T. The behaviour of the thermostat is investigated as a function of the thermal inertia and its appropriate range is determined by evaluating the kinetic energy fluctuations.
