Buch. Etat : Neu. Druck auf Anfrage Neuware - Printed after ordering - This book provides a comprehensive overview of the current density-functional theory (DFT) for electrons in atoms and molecules, as well as a detailed review of the new formalism of the DFT. In the conventional DFT, the spatial electron distribution plays an essential role in describing the electronic properties of the system under consideration. In contrast, the electron distribution on the energy coordinate defined by the external potential applied to the electrons serves as a fundamental variable in the foundation of the new DFT. In this book, a particular emphasis is placed on the discussion on the advantage of the new theory in solving the toughest problems in the current DFT. Specifically, it is demonstrated that the new theory has a potential to solve the static correlation errors which arise in describing chemical bonds using the current DFT based on the single electronic configurations. Some prototypes of the functionals are developed in the book, which realize the static correlations. The theory is also utilized to develop the kinetic energy functional known as the most difficult issue in DFT. The book offers useful explanations of the new theory for the researchers and students to understand and apply it to future developments.…

Taschenbuch. Etat : Neu. Druck auf Anfrage Neuware - Printed after ordering - This book is an outcome of the International Workshop on Electronic Density Functional Theory, held at Griffith University in Brisbane, Australia, in July 1996. Density functional theory, standing as it does at the boundary between the disciplines of physics, chemistry, and materials science, is a great mixer. Invited experts from North America, Europe, and Australia mingled with students from several disciplines, rapidly taking up the informal style for which Australia is famous. A list of participants is given at the end of the book. Density functional theory (DFT) is a subtle approach to the very difficult problem of predicting the behavior of many interacting particles. A major application is the study of many-electron systems. This was the workshop theme, embracing inter alia computational chemistry and condensed matter physics. DFT circumvents the more conceptually straightforward (but more computationally intensive) approach in which one solves the many-body Schrodinger equation. It relies instead on rather delicate considerations involving the electron number density. For many years the pioneering work of Kohn and Sham (the Local Density Ap proximation of 1965 and immediate extensions) represented the state of the art in DFT. This approach was widely used for its appealing simplicity and computability, but gave rather modest accuracy. In the last few years there has been a renaissance of interest, quite largely due to the remarkable success of the new generation of gradient functionals whose initiators include invitees to the workshop (Perdew, Parr, Yang).…

Hardback. Etat : New. Density functional theory (DFT) is today's most widely used method for practical computational electronic structure calculations across chemistry, physics and materials science. It is not only the first choice for running simulations, but it has also delivered an alternative view-point for thinking about the electronic structure of an enormous range of molecular and solid state systems. Fuelled by a rapid increase in computational power and the advent of linear scaling technologies the systems to which DFT may be applied have become ever larger, more complex and more diverse. This rapid growth in the range of problems that may be subjected to computational study has often highlighted new challenges for DFT methodologies in terms of accuracy, speed and scope, spurring many new developments in the field.This Faraday Discussions volume is for chemists, physicists, materials scientists and applied mathematicians who develop new density-functional methods and rely on this approach as a key tool in their research. By discussing the latest cutting edge developments and their relative merits this volume should help bring these new methods to practical application quickly and effectively. It focuses on the following four themes:New density-functional approximations and beyondChallenges for large scale simulationStrong correlation in density-functional theoryNew approaches to study excited states in density-functional theory.…
