False vacuum decay in the early Universe and gravitational waves

2015年，LIGO/Virgo合作首次直接观测到双子星并合产生的引力波。在未来十年，引力波研究将进入精密科学的领域。这对粒子物理学来说是一个巨大的机遇，但要正确地解释这些数据，还有很多事情需要了解。为了最大限度地提高我们的发现潜力，必须开发新的分析和计算工具来将实验发现转化为有关粒子的信息。在这个项目中，我们将主要关注引力波的早期宇宙源（正如计划中的LISA实验可能观察到的那样），特别是一阶相变。来自这些来源的引力波有可能解开我们宇宙的许多谜团，包括暗物质的本质、强cp问题，以及物质和反物质之间的不对称性。

The first direct observation of gravitational waves from a binary merger was made by the LIGO/Virgo collaboration in 2015. In the next decade, gravitational wave research will enter the realm of precision science. This is a big opportunity for particle physics, but much still needs to be understood to properly interpret the data. To maximize our discovery potential, new analytic and computational tools have to be developed to translate the experimental findings to information about particles. In this project we will mostly focus on early Universe sources of gravitational waves (as may be observed by the planned LISA experiment), in particular from first order phase transitions. Gravitational waves from these sources hold the potential to unravel many mysteries of our Universe, including the nature of dark matter, the strong CP-problem, and the asymmetry between matter and antimatter.
