Fig. 3
Upper panel: absolute value of the potential energy in physical coordinates Wp(a) (Eq. (16)) as a function of the scale factor. The approximate value of aLI, separating the regime where Wp ≈ const. from the one where | Wp | ~ a-1, is reported as reference. Bottom panel: LI test (Eq. (26)) and virial ratio (absolute value) for particles with negative energy.
