A Study of the Early Cosmic Dynamics in a Multifield Model of Inflation and Curvature Perturbations

Figure 4

The figure demonstrates the mass distribution according to the Marčhenko–Pastur law as it takes place against the dimensionless mass variables in the case that takes on different values. The parameter is along the parallel axis when the functions are along vertical axes. It can be noted that the law of large numbers of mass scales ensures that the mass distribution of fields obeys the distribution probability similar to that of a single field. the (a) plot is simply presented, (b) it is drawn after taking its logarithm.
