Motivated by the link between Anderson localisation on high-dimensionalgraphs and many-body localisation, we study the effect of periodic driving onAnderson localisation on random trees. The time dependence is eliminated infavour of an extra dimension, resulting in an extended graph wherein thedisorder is correlated along the new dimension. The extra dimension increasesthe number of paths between any two sites and allows for interference betweentheir amplitudes. We study the localisation problem within the forwardscattering approximation (FSA) which we adapt to this extended graph. At lowfrequency, this favours delocalisation as the availability of a large number ofextra paths dominates. By contrast, at high frequency, it stabiliseslocalisation compared to the static system. These lead to a regime ofre-entrant localisation in the phase diagram. Analysing the statistics of pathamplitudes within the FSA, we provide a detailed theoretical picture of thephysical mechanisms governing the phase diagram.
