    "abstract": "Chains of parametrically driven, damped pendula are known to support\nsoliton-like clusters of in-phase motion which become unstable and seed\nspatiotemporal chaos for sufficiently large driving amplitudes. We show that\nthe pinning of the soliton on a \"long\" impurity (a longer pendulum) expands\ndramatically its stability region whereas \"short\" defects simply repel solitons\nproducing effective partition of the chain. We also show that defects may\nspontaneously nucleate solitons.",
