Available in PDF, EPUB and Kindle. Book excerpt: This volume is a collection of papers presented at the Fifteenth International Conference on Ultrafast Phenomena held at the Asilomar Conference Grounds, Pacifc Grove, CA, USA, from July 31 – August 4, 2006. The Ultrafast P- nomena conferences are held every two years and provide a forum for disc- sion of the latest results in ultrafast optics and their applications in science and engineering. These meetings bring together researchers spanning several felds of science and engineering to discuss and debate the latest advances in ult- fast science. This unique forum provides a conduit for the greater dissemi- tion of the latest advances using ultrashort coherent pulses of light. More than 280 papers were presented. Signifcant progress in creating ever shorter pulses of light was reported in the attosecond range, with new applications in high harmonic generation and frequency comb metrology. Multidimensional sp- troscopy is rapidly evolving to provide new insights into quantum coherence and interactions in complex systems. Improvements in time resolved electron and x-ray diffraction provide better atomic scale perspectives on structural dynamics. These examples are but a small subset of the collected works ga- ered in this volume, which provides a valuable synopsis of the recent advances and impact of ultrafast technology in illuminating fundamental processes in physics, chemistry, and biology. There were 323 attendees at the meeting, more than one third of which were graduate and postdoctoral students. Increased s- dent attendance energized the proceedings.

Download or read book Ultrafast Dynamics at the Nanoscale written by Stefan Haacke and published by CRC Press. This book was released on 2017-01-06 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrafast Dynamics at the Nanoscale provides a combined experimental and theoretical insight into the molecular-level investigation of light-induced quantum processes in biological systems and nanostructured (bio)assemblies. Topics include DNA photostability and repair, photoactive proteins, biological and artificial light-harvesting systems, plasmonic nanostructures, and organic photovoltaic materials, whose common denominator is the key importance of ultrafast quantum effects at the border between the molecular scale and the nanoscale. The functionality and control of these systems have been under intense investigation in recent years in view of developing a detailed understanding of ultrafast nanoscale energy and charge transfer, as well as fostering novel technologies based on sustainable energy resources. Both experiment and theory have made big strides toward meeting the challenge of these truly complex systems. This book, thus, introduces the reader to cutting-edge developments in ultrafast nonlinear optical spectroscopies and the quantum dynamical simulation of the observed dynamics, including direct simulations of two-dimensional optical experiments. Taken together, these techniques attempt to elucidate whether the quantum coherent nature of ultrafast events enhances the efficiency of the relevant processes and where the quantum–classical boundary sets in, in these high-dimensional biological and material systems. The chapters contain well-illustrated accounts of the authors’ research work, including didactic introductory material, and address a multidisciplinary audience from chemistry, physics, biology, and materials sciences. The book is, therefore, a must-have for graduate- and postgraduate-level researchers who wish to learn about molecular nanoscience from a combined spectroscopic and theoretical viewpoint.

Download or read book Dynamics of Molecular Excitons written by Seogjoo J. Jang and published by Elsevier. This book was released on 2020-04-25 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamics of Molecular Excitons provides a comprehensive, but concise description of major theories on the dynamics of molecular excitons, intended to serve as a self-contained resource on the topic. Designed to help those new to this area gain proficiency in this field, experts will also find the book useful in developing a deeper understanding of the subject. The starting point of the book is the standard microscopic definition of molecular Hamiltonians presented in commonly accepted modern quantum mechanical notations. Major assumptions and approximations involved in constructing Frenkel-type exciton Hamiltonians, which are well established, but are often hidden under arcane notations and approximations of old publications, are presented in detail. This will help quantum chemists understand the major assumptions involved in the definition of commonly used exciton models. Rate theories of exciton dynamics, such as Förster and Dexter theories and their modern generalizations, are presented in a unified and detailed manner. In addition, important aspects that are often neglected, such as local field effect and the role of fluctuating environments, are discussed. Various quantum dynamics methods allowing coherent dynamics of excitons are presented in a systematic manner in the context of quantum master equations or path integral formalisms. The author also provides a detailed theoretical explanation for the major spectroscopic techniques probing exciton dynamics, including modern two-dimensional electronic spectroscopy, with a critical assessment of the implications of these spectroscopic measurements. Finally, the book includes a brief overview of major applications including an explanation of organic photovoltaic materials and natural light harvesting complexes. - Covers major theories of exciton dynamics in a consciously concise and easily readable way - Bridges the gap between quantum dynamics working with phenomenological exciton Hamiltonian and quantum chemistry construct reliable models amenable for dynamics calculations from ab initio calculations - Explores modern nonlinear electronic spectroscopy techniques to probe exciton dynamics, showing how it is applied

Download or read book Optical Properties of Excited States in Solids written by Baldassare di Bartolo and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 749 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an account of the course "Optical Properties of Excited States in Solids" held in Erice, Italy, from June 16 to 3D, 1991. This meeting was organized by the International School of Atomic and Molecular Spectroscopy of the "Ettore Majorana" Centre for Scientific Culture. The purpose of this course was to present physical models, mathematical formalisms and experimental techniques relevant to the optical properties of excited states in solids. Some active physical species, such as ions or radicals, could survive indefinitely if they were completely 'isolated in space. Other active species, such as excited molecular and solid-state systems, are inherently unstable, even in isolation, due to the spontaneous mechanisms that may convert their excitation energies into radiation or heat. Physical parameters that may be used to characterize these excited systems are the localization or delocalization, and the coherence or incoherence, of their state excitations. In solids the excited states, whether they are localized (as for impurities in insulators) or delocalized (as they may occur in semiconductors), are relevant in several regards. Their de-excitation is extremely sensitive to the nature of the excitations of the systems, and a study of the de-excitation processes can yield a variety of information. For example, the excited states may represent the initial condition of the onset of such processes as Stokes-shifted emission, hot luminescence, symmetry-dependent Jahn-Teller and scattering processes, tunneling processes, energy transfer to like and unlike centers, superradiance, coherent radiation, and excited state absorption.
