Particle numberʼs evolutions of the two components in regime of [−35,35], where the particle transition happens. The blue dotted line represents bubble component, the green dashed line represents droplet component, and the thick red line represents total number of particles in this regime. The parameters are λ 1 = − 0.5 , λ 2 = 0.5 , k 1 = k 2 = 1 , c 1 = c 2 = 2 , α 1 = α 2 = 0 .
