In previous work we established a phase transition for this model on the integers in the case of Pareto distributed potential with parameter $\\alpha > 1$ and fixed duplication probability $p \\in (0, 1)$: if $\\alpha \\ge 2$ the model completely localises, whereas if $\\alpha \\in (1, 2)$ the model may localise on two sites.
