Minimum value of the eigenvalue L at given Ξ (the dimensionless radius characterizing the system) as a function of Ξ, for the constant { T,V } case. If the minimum L is negative then the system is unstable. The system becomes unstable at Ξ = 8.99, the same value obtained from the thermodynamical approach. From the figure we can read the typical time scale of the instability. As Ξ → ∞, the asymptotic value L =  −0.042 is the same as for the other cases (see Figs. 3 and 4).
