The average number of contacts 〈z〉 plotted (A) as a function of time after quenching for glassy globules (ε = 10) with different chain lengths. (B) as a function of radial distance rcentre outwards from the centre of mass for glassy globules (ε = 10) with a range of different chain lengths. Displacements are calculated at 1000τ after the reference time of t = 3 × 105τ, (when the globule has achieved its compact state) and are averaged over all particles in each shell. (C) A plot of enthalpy (an equivalent of the total energy of the system) for glassy globules (ε = 10) as a function of temperature demonstrating the same Tg ≈ 1.5 for differently bonded systems (dimers, dimer-equivalent set and a single chain).
