We study a generalization of the one-dimensional disordered Potts model, which exhibits glassy properties at low temperature. The real-space properties of inherent structures visited dynamically are analyzed through a decomposition into domains over which the energy is minimized. The size of these domains is distributed exponentially, defining a characteristic length scale which grows in equilibrium when lowering temperature, as well as in the aging regime at a given temperature. In the low-temperature limit, this length can be interpreted as the distance between “excited” domains within the inherent structures.
