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

点击翻译按钮获取中文摘要

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.
