论文摘要
早期宇宙中的一阶相变自然会导致重力波的随机背景产生，并产生物质抗逆不是对称性的物质抗对称性。相变的动力学受热等离子体中的密度扰动的影响。我们通过首次提供对线性化的Boltzmann方程的完整数值解决方案来解决此主题，用于在Electroweak量表的一阶相变期间与Higgs磁场相连的顶部夸克物种。与传统方法不同，我们的结果不取决于任何ANSATZ，并且可以充分描述血浆中粒子物种的非平衡分布函数。
First order phase transitions in the early universe naturally lead to the production of a stochastic background of gravitational waves and to the generation of a matter-antimatter asymmetry. The dynamics of the phase transition is affected by the density perturbations in the hot plasma. We address this topic by providing, for the first time, a full numerical solution to the linearized Boltzmann equation for the top quark species coupled to the Higgs field during a first order phase transition at the electroweak scale. Differently from the traditional approaches, our results do not depend on any ansatz and can fully describe the non-equilibrium distribution functions of the particle species in the plasma.
