Primary events in natural systems or devices occur on extremely short time scales, and yet determine in many cases the final performance or output. For this reason research in ultrafast science is of primary importance and impact in both fundamental research as well as its applications. This book reviews the advances in the field, addressing timely and open questions such as the role of quantum coherence in biology, the role of excess energy in electron injection at photovoltaic interfaces or the dynamics in quantum confined structures (e.g. multi carrier generation). The approach is that of...

This volume presents research and expository articles by the participants of the 25th Arkansas Spring Lecture Series on Recent Progress in the Study of Harmonic Measure from a Geometric and Analytic Point of View held at the University of Arkansas, USA. Papers in this volume provide presentations of the problems that are at the forefront of harmonic analysis and partial differential equations. The following topics are featured: the solution of the Kato conjecture, the two bricks problem, new results on Cauchy integrals on non-smooth curves, the Neumann problem for sub-Laplacians, and a...
