To better understand the details of the analysis in Sec. 11.2, reproduce Fig. 11.8 which corresponds to a slightly different choice of parameters, namely a = −1.48 instead of a = −4/3, than used for Fig. 11.4, leading to a less symmetric case. The dashed straight line in Fig. 11.8 touching the dashed curve representing ƒ(ρ) for β = 2.8 indicates how one may graphically solve Eq. (11.28). Use this to determine the segregation transition to determine the roots of Eq. (11.28) as a function of β.
