  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.
