The characteristics of second-order QPT for the present system in Eq. (1). (a) Plots of ∂2Eg/∂η2 as a function of η for different values of N, (b) the scaling law of pseudo critical point ηm as a function of N, (c) the scaling law of the (∂2Eg/∂η2)m as a function of N. The parameters for all plots are M = 7 and ϕ = π/4.
