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 F├╢rster 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 wayBridges the gap between quantum dynamics working with phenomenological exciton Hamiltonian and quantum chemistry construct reliable models amenable for dynamics calculations from ab initio calculationsExplores modern nonlinear electronic spectroscopy techniques to probe exciton dynamics, showing how it is applied

Light, Plasmonics and Particles focuses on the fundamental science and engineering applications of light scattering by particles, aerosols and hydrosols, and of localized plasmonics. The book is intended to be a self-contained and coherent resource volume for graduate students and professionals in the disciplines of materials science, engineering and related disciplines of physics and chemistry. In addition to chapters related to fundamental concepts, it includes detailed discussion of different numerical models, experimental systems and applications. In order to develop new devices, processes and applications, we need to advance our understanding of light-matter interactions. For this purpose, we need to have a firm grasp of electromagnetic wave phenomena, and absorption and scattering of waves by different size and shape geometrical objects. In addition, understanding of tunneling of waves based on electron and lattice vibrations and coupling with the thermal fluctuations to enhance near-field energy transfer mechanisms are required for the development of future energy harvesting devices and sensors.
