Schematic illustration of a PEL that arises from the disordered nature of the force network and its inherent fluctuations.
The bottom of each basin corresponds to a given realisation of the force network. The three packings Ψi, Ψj, Ψk are calculated in Fig. 2. The energy barriers between the basins are depicted schematically. The barrier-crossing event leads to a constrained configuration change of the force networks.
