Dimensional scaling offers a new approach to quantum dynamical correlations. This is the first book dealing with dimensional scaling methods in the quantum theory of atoms and molecules. Appropriately, it is a multiauthor production, derived chiefly from papers presented at a workshop held in June 1991 at the Ørsted Institute in Copenhagen. Although focused on dimensional scaling, the volume includes contributions on other unorthodox methods for treating nonseparable dynamical problems and electronic correlation. In shaping the book, the editors serve three needs: an introductory tutorial for this still fledgling field; a guide to the literature; and an inventory of current research results and prospects. Part I treats basic aspects of dimensional scaling. Addressed to readers entirely unfamiliar with the subject, it provides both a qualitative overview, and a tour of elementary quantum mechanics. Part II surveys the research frontier. The eight chapters exemplify current techniques and outline results. Part III presents other methods, including nonseparable dynamics, and electron correlation in pseudomolecular excited states of atoms. Although procrustean conformity was not imposed, unifying and complementary themes are emphasized throughout the book.

This book provides a broad description of the development and (computational) application of many-electron approaches from a multidisciplinary perspective. In the context of studying many-electron systems Computer Science, Chemistry, Mathematics and Physics are all intimately interconnected. However, beyond a handful of communities working at the interface between these disciplines, there is still a marked separation of subjects. This book seeks to offer a common platform for possible exchanges between the various fields and to introduce the reader to perspectives for potential further developments across the disciplines. The rapid advances of modern technology will inevitably require substantial improvements in the approaches currently used, which will in turn make exchanges between disciplines indispensable. In essence this book is one of the very first attempts at an interdisciplinary approach to the many-electron problem.

The Schr”dinger equation is the master equation of quantum chemistry. The founders of quantum mechanics realised how this equation underpins essentially the whole of chemistry. However, they recognised that its exact application was much too complicated to be solvable at the time. More than two generations of researchers were left to work out how to achieve this ambitious goal for molecular systems of ever-increasing size. This book focuses on non-mainstream methods to solve the molecular electronic Schr”dinger equation. Each method is based on a set of core ideas and this volume aims to explain these ideas clearly so that they become more accessible. By bringing together these non-standard methods, the book intends to inspire graduate students, postdoctoral researchers and academics to think of novel approaches. Is there a method out there that we have not thought of yet? Can we design a new method that combines the best of all worlds?

Examines the intersection of quantum information and chemical physics The Advances in Chemical Physics series is dedicated to reviewing new and emerging topics as well as the latest developments in traditional areas of study in the field of chemical physics. Each volume features detailed comprehensive analyses coupled with individual points of view that integrate the many disciplines of science that are needed for a full understanding of chemical physics. This volume of the series explores the latest research findings, applications, and new research paths from the quantum information science community. It examines topics in quantum computation and quantum information that are related to or intersect with key topics in chemical physics. The reviews address both what chemistry can contribute to quantum information and what quantum information can contribute to the study of chemical systems, surveying both theoretical and experimental quantum information research within the field of chemical physics. With contributions from an international team of leading experts, Volume 154 offers seventeen detailed reviews, including: Introduction to quantum information and computation for chemistry Quantum computing approach to non-relativistic and relativistic molecular energy calculations Quantum algorithms for continuous problems and their applications Photonic toolbox for quantum simulation Vibrational energy and information transfer through molecular chains Tensor networks for entanglement evolution Reviews published in Advances in Chemical Physics are typically longer than those published in journals, providing the space needed for readers to fully grasp the topic: the fundamentals as well as the latest discoveries, applications, and emerging avenues of research.

Symmetry Adapted Basis Sets written by John Avery and has been published by World Scientific this book supported file pdf, txt, epub, kindle and other format this book has been release on 2012 with Science categories.

In theoretical physics, theoretical chemistry and engineering, one often wishes to solve partial differential equations subject to a set of boundary conditions. This gives rise to eigenvalue problems of which some solutions may be very difficult to find. For example, the problem of finding eigenfunctions and eigenvalues for the Hamiltonian of a many-particle system is usually so difficult that it requires approximate methods, the most common of which is expansion of the eigenfunctions in terms of basis functions that obey the boundary conditions of the problem. The computational effort needed in such problems can be much reduced by making use of symmetry-adapted basis functions. The conventional method for generating symmetry-adapted basis sets is through the application of group theory, but this can be difficult. This book describes an easier method for generating symmetry-adapted basis sets automatically with computer techniques. The method has a wide range of applicability, and can be used to solve difficult eigenvalue problems in a number of fields. The book is of special interest to quantum theorists, computer scientists, computational chemists and applied mathematicians.

Benjamin Bederson contributed to the world of physics in many areas: in atomic physics, where he achieved renown by his scattering and polarizability experiments, as the Editor-in-Chief for the American Physical Society, where he saw the introduction of electronic publishing and a remarkable growth of the APS journals, with ever increasing world-wide contributions to these highly esteemed journals, and as the originator of a number of international physics conferences in the fields of atomic and collision physics, which are continuing to this day. Bederson was also a great teacher and university administrator. The first part of this volume of Advances in Atomic, Molecular, and Optical Physics (AAMOP), entitled Benjamin Bederson: Works, Comments and Legacies, contains articles written from a personal perspective. His days at Los Alamos during World War II, working on the A bomb, are recounted by V. Fitch. H. Walther writes on the time when both were editors of AAMOP. H. Lustig, E. Merzbacher and B. Crasemann, with whom Bederson had a long-term association at the American Physical Society, contribute their experiences, one of them in the style of a poem. C.D. Rice recalls his days when he was Dean of the Faculty of Arts and Science at NYU, and the education in physics that he received from Bederson, then Dean of the Graduate School. The contribution by R. Stuewer is on Bederson as physicist historian (his latest interest). N. Lane draws some parallels between "two civic scientists, Benjamin Bederson and the other Benjamin". The papers are introduced by H.H. Stroke, in an overview of Bederson's career. A biography and bibliography are included. The second part of the volume contains scientific articles on the Casimir effects (L. Spruch), dipole polarizabilities (X. Chu, A. Dalgarno), two-electron molecular bonds revisited (G. Chen, S.A. Chin, Y. Dou, K.T. Kapale, M. Kim, A.A. Svidzinsky, K. Uretkin, H. Xiong, M.O. Scully, and resonance fluorescence of two-level atoms (H. Walther). J. Pinard and H.H. Stroke review spectroscopy with radioactive atoms. T. Miller writes on electron attachment and detachment in gases, and, with H. Gould, on recent developments in the measurement of static electric dipole polarizabilities. R. Celotta and J.A. Stroscio's most recent work on trapping and moving atoms on surfaces is contributed here. C.C. Lin and J.B. Borrard's article is on electron-impact excitation cross sections. The late Edward Pollack wrote his last paper for this volume, Atomic and Ionic Collisions. L. Vuskovic and S. Popovi ́c write on atomic interactions in a weakly ionized gas and ionizing shock waves. The last scientific article is by H. Kleinpoppen, B. Lohmann, A. Grum-Grzhimailo and U. Becker on approaches to perfect/complete scattering in atomic and molecular physics. The book ends with an essay on teaching by R.E. Collins. - Benjamin Bederson - Atomic Physicist, Civil Scientist - The Physical Review and Its Editor - Los Alamos in World War II - View from Below - Physics in Poetry - Casimir Effects - Pedagogical Notes - Atomic Physics in Collisions, Polarizabilities, Gases, Atomic Physics and Radioactive Atoms - Molecular Bond Revisited - Resonance Fluorescence in 2-Level Atoms - Trapping and Moving Atoms on Surfaces
