Abstract

We study numerically the evolution of an expanding system of scalar fields. The initial configuration is non-isotropic and rotating. We calculate the energy-momentum tensor and angular momentum vector of the system. We compare the time scales associated with the isotropization of the transverse and longitudinal pressures, and the decay of the initial angular momentum. We show that even a fairly large initial angular momentum decays significantly faster than the pressure anisotropy.

摘要

我们对一个标量场膨胀系统的演化进行了数值研究。初始构型是非各向同性且旋转的。我们计算了该系统的能量 - 动量张量和角动量矢量。我们比较了与横向和纵向压力各向同性化以及初始角动量衰减相关的时间尺度。我们表明，即使是相当大的初始角动量，其衰减速度也比压力各向异性快得多。
