A New Mechanism for Generating Particle Number Asymmetry through Interactions

Figure 2

Dependence on parameter of the time evolution of PNA. The horizontal axis is the dimensionless time defined as . As a reference angular frequency, we choose . We fix a set of parameters as () = () for all of the lines. The purple, thin purple, dotted purple, black, dashed purple, and dot-dashed purple lines show the cases and , respectively.
