Abstract
Cosmology is the study of the early universe as a dynamical system. In the early universe, we predict a period of cosmic inflation, or the rapid expansion of the universe, which leaves it cold and empty. Preheating provides a solution for thermalizing the universe and allowing for big bang nucleosynthesis to occur, which creates the universe we see today. Gauge preheating has been studied as a potential form of preheating, and its basis is centered around creating a rapid, violent process that transfers energy from the inflaton field, ϕ, to a gauge field Aμ. A consequence of using gauge fields is they must be a consequence of and coupled to charged particles in order for a radiation dominated universe and therefore big bang nucleosynthesis to occur. Here we use complex scalar fields as our charged particles to predict how efficient gauge preheating can be in the presence of these particles.
