论文摘要
我们对气泡壁进行大规模的实时模拟，该模拟通过过平衡的等离子体扫描。我们想到的情况是electroweak相转换，在标准模型的扩展中可能是一阶，并产生这样的气泡。该过程可能是导致男性生成的原因，并且可以产生原始宇宙学引力波的背景。我们研究了前进壁附近血浆的热力学特征，Chern-Simons编号/higgs绕组数的产生，并考虑在壁上产生Baryon不对称性的CP侵入的潜力。开发了适当的数值实施所需的许多技术细节。
We perform large-scale real-time simulations of a bubble wall sweeping through an out-of-equilibrium plasma. The scenario we have in mind is the electroweak phase transition, which may be first order in extensions of the Standard Model, and produce such bubbles. The process may be responsible for baryogenesis and can generate a background of primordial cosmological gravitational waves. We study thermodynamic features of the plasma near the advancing wall, the generation of Chern-Simons number/Higgs winding number and consider the potential for CP-violation at the wall generating a baryon asymmetry. A number of technical details necessary for a proper numerical implementation are developed.
