We present the results of General Relativistic Magnetohydrodynamic simulations utilizing initial conditions from both the Electroweak and Quantum Chromodynamic (QCD) phase transitions in order to determine if seed magnetic fields may be generated via the Biermann Battery Mechanism of Magnetogenesis. These simulations occur in a simulated early universe between 10⁻¹¹ s and 10³ s after the Big Bang. We find that magnetic fields greater than 10⁻²⁰ G may be generated on the Mpc scale. This is believed to be strong enough to generate the large intergalactic magnetic fields seen today. Further work is needed to understand how these fields may have impacted the large‐scale structures we currently observe.

宇宙早期相变磁化作用的数值分析

我们介绍了利用相对弱的电磁场和量子色动力学（QCD）相变的初始条件进行的一般相对论磁流体动力学模拟的结果，以确定是否可以通过Biermann电池机制来产生种子磁场。这些模拟发生在 大爆炸之后10 ^-11  s和10 ³ s之间的模拟早期宇宙中。我们发现， 在Mpc尺度上可能会产生大于10 ^-20 G的磁场。据信，这种强度足以产生当今所见的大星系间磁场。需要做进一步的工作来了解这些领域可能如何影响我们目前观察到的大型结构。
