We present exact results for the spectrum of the fractional Laplacian in a bounded domain and apply them to First-Passage-Time (FPT) statistics of Levy flights. We specifically show that the average is insufficient to describe the distribution of the FPT, although it is the only quantity available in the existing literature. In particular, we show that the FPT distribution is not peaked around the average, and that knowledge of the whole distribution is necessary to describe this phenomenon. For this purpose, we provide an efficient method to calculate higher-order cumulants and the whole distribution. Copyright (C) EPLA, 2008.
