标题： Gauge Field Turbulence as a Cause of Inflation in Chern-Simons Modified Gravity

摘要： 在本文中，我们研究了Alexander、Marciano和Spergel提出的Chern-Simons暴胀模型的动力学特性。 根据该模型，当费米子电流与一个比某些临界尺寸更大的空间中的湍流规范场相互作用时，暴胀开始。 这种机制似乎通过将初始随机谱的能量驱动到一个狭窄的频率带中来工作，类似于MHD湍流中观察到的反向能量级联。 在本工作中，我们专注于使用相图和对演化方程的详细分析来研究相互作用的动力学。 我们表明，在该模型中，暴胀是由一个过阻尼谐振子在规范场的共振频率处驱动波引起的。 显示英文摘要

摘要： In this paper, we study the dynamics of the Chern-Simons Inflation Model proposed by Alexander, Marciano and Spergel. According to this model, inflation begins when a fermion current interacts with a turbulent gauge field in a space larger than some critical size. This mechanism appears to work by driving energy from the initial random spectrum into a narrow band of frequencies, similar to the inverse energy cascade seen in MHD turbulence. In this work we focus on the dynamics of the interaction using phase diagrams and a thorough analysis of the evolution equations. We show that in this model inflation is caused by an over-damped harmonic oscillator driving waves in the gauge field at their resonance frequency.
