Non-Equilibrium Phase Transitions : From Chiral Condensates to the Early Universe

布鲁克海文和欧洲核子研究中心的新实验将在高温和高密度下探测物质，这只有在宇宙演化的早期阶段才能实现。 下一代的天体物理学实验也将通过宇宙微波背景中各向异性的物理过程留下的印记，提供早期宇宙物理学的一瞥。 粒子物理学预测，在宇宙的早期，发生了几次相变，这些相变是造成这些各向异性的原因。 我的项目是开发和实现非平衡量子物理学的工具，以提供这些相变的动力学的详细分析。 目标是能够识别和量化它们的宇宙学后果及其实验特征，并将理论预测与通过这些新实验获得的实验数据进行比较。 人们已经认识到，只有远离平衡的一致研究才能有效地解决早期宇宙中发生的极端环境的物理学问题。

New experiments at Brookhaven and CERN will probe matter at high temperatures and densities, achieved only during the very early stages of evolution of the Universe. The next generation of Astrophysical experiments will also offer a glimpse of the Physics of the Early Universe through the imprint left by the physical processes as anisotropies in the Cosmic Microwave Background. Particle Physics predicts that several phase transitions have occurred during the very Early Universe that are responsible for these anisotropies. My project is to develop and implement the tools of non-equilibrium quantum physics to provide a detailed analysis of the dynamics of these phase transitions. The goal is to be able to recognize and quantify their Cosmological consequences and their experimental signatures and to compare predictions from theories to the experimental data that will become available through these new experiments. It has been recognized that only a consistent study away from equilibrium can address effectively the Physics of the extreme environments that has taken place in the Early Universe.
