来自宇宙学相变的引力波

Gravitational waves from cosmological phase transitions

Ruth Durrer

摘要:

讨论了一阶相变过程中引力波随机背景的产生。我提出了简单的一般性论点,解释了引力波的主要特点,如$k^3$幂律增长的大尺度和峰值振幅的估计。在第二部分中,我集中在电弱相变,并认为核合成绑定在其引力波背景严重限制种子磁场,这可能已经产生在这个过渡。

英文摘要:

I discuss the generation of a stochastic background of gravitational waves during a first order phase transition. I present simple general arguments which explain the main features of the gravitational wave spectrum like the $k^3$ power law growth on large scales and a estimate for the peak amplitude. In the second part I concentrate on the electroweak phase transition and argue that the nucleosynthesis bound on its gravitational wave background seriously limits seed magnetic fields which may have been generated during this transition.
