Description
During inflation, the inflaton can undergo significant changes. If the inflaton field is coupled to other fields, phase transitions may occur in the coupled fields as the inflaton evolves. The curvature perturbations and gravitational waves generated by the phase transition may be detectable and could provide insights about inflation. We explore the possible curvature perturbation and the secondary GW generated by a U(1) symmetry breaking during inflation. We computed the shape characteristics of curvature perturbations and gravitational waves through numerical simulations. In the future, we may be able to understand early universe processes by experimentally observing these physical quantities.
