For describing the local structure of a random self{similar measure we use the multi-fractal decomposition of its support into sets of points of diierent local dimension. Under the strong open set condition we compute the Hausdorr dimensions of these sets and the generalized dimensions of the random self{similar measure. Furthermore, the tangential(More)
When an excited atom is embedded into an environment, novel relaxation pathways can emerge that are absent for isolated atoms. A well-known example is interatomic Coulombic decay, where an excited atom relaxes by transferring its excess energy to another atom in the environment, leading to its ionization. Such processes have been observed in clusters(More)
Near-fields of non-resonantly laser-excited nanostructures enable strong localization of ultrashort light fields and have opened novel routes to fundamentally modify and control electronic strong-field processes. Harnessing spatiotemporally tunable near-fields for the steering of sub-cycle electron dynamics may enable ultrafast optoelectronic devices and(More)
