Abstract: We discuss massive scalar perturbations of a Schwarzschild black hole. Weargue that quantum effects alter the effective potential near the horizonresulting in Poincare recurrences in Green functions. Results at thesemi-classical level are independent of the details of the modification of thepotential provided its minimum near the horizon is inversely proportional tothe square of the Poincare time. This modification may be viewed as a change inthe near-horizon geometry. We consider explicitly the examples of a brick wall,a smooth cutoff and a wormhole-like modification showing that they all lead tothe same results at leading order.
