This practical book presents an overview of the various approaches developed to understand the dynamics of electronic systems in physics and chemistry. It also illustrates typical application examples, namely atoms, molecules, and clusters such as nano objects. For each system, the book reviews its key features and concepts and also provides a wider perspective on other physical systems such as atomic nuclei and quantum dots.There exist a large number of theories adapted to specific physical situations (both in space and time), but there is not yet a common theory for all possible dynamical scenarios. This book provides a general perspective on the topic, supplying the reader with a guidebook to navigate the wide spectrum of approaches.It provides an overview of available theories to address various problems in the irradiation of finite systems, discussing the possibilities and limitations of the available theories to help readers understand the applicability of a given theory or set of theories to address a given physical problem or chemical situation.It is an ideal guide for graduate students and researchers in physics and chemistry.Key Features:Presents a critical survey of available theoretical tools to help readers choose the appropriate method or approach for any given physical situationsAccessible, with an emphasis on avoiding details of formal and technical difficultiesProvides a guided tour based on typical examples starting from the actual physical situation down to actual tools to be used to describe it

Electronic structure problems are studied in condensed matter physics and theoretical chemistry to provide important insights into the properties of matter. This 2006 graduate textbook describes the main theoretical approaches and computational techniques, from the simplest approximations to the most sophisticated methods. It starts with a detailed description of the various theoretical approaches to calculating the electronic structure of solids and molecules, including density-functional theory and chemical methods based on Hartree-Fock theory. The basic approximations are thoroughly discussed, and an in-depth overview of recent advances and alternative approaches in DFT is given. The second part discusses the different practical methods used to solve the electronic structure problem computationally, for both DFT and Hartree-Fock approaches. Adopting a unique and open approach, this textbook is aimed at graduate students in physics and chemistry, and is intended to improve communication between these communities. It also serves as a reference for researchers entering the field.
