Show affiliationsWe investigate the evolution of the nonlinear long wavelength fluctuations during preheating after inflation. By using the separate universe approach, the temporal evolution of the power spectrum of the scalar fields and the curvature variable is obtained numerically. We found that the amplitude of the large-scale fluctuations is suppressed after nonlinear evolution during preheating.
