Theoretical Studies of Topics in Phase Transitions in the Early Universe

[406745] Freese在理论天体物理学方面的研究将涉及对早期宇宙中发生的相变的检验。研究了两种具体现象。第一个问题涉及宇宙开始后不久的快速膨胀，研究的重点是这种膨胀的机制。第二个是关于夸克与普通粒子结合所产生的效应。该领域的研究重点是伴随这一转变而形成的“弦状”物体。这项工作的结果为宇宙演化的关键时期所发生的事情提供了一幅更清晰的图景。＊＊＊

9406745 Freese Research in theoretical astrophysics will involve an examination of the occurrence of phase transitions in the early universe. Two specific phenomena are studied. The first concerns the rapid expansion of the universe not long after its beginning, and the research focuses on the mechanism for this inflation. The second concerns the effects arising from the binding of quarks into ordinary particles. Research in this area focuses on the formation of "stringy" objects that accompany this transition. The results of the work provide a clearer picture of what happens during a critical period in the evolution of the universe. ***
