Available in PDF, EPUB and Kindle. Book excerpt: Downfolding Methods in Many-Electron Theory is a comprehensive description of the last 30 years of study in this field, starting from LDA+U to LDA+DMFT and arriving at the recent work on multitier self-consistent GW+EDMFT. It focuses on different levels of first-principles electronic structure theories for strongly correlated electrons and outlines the downfolding method as a general approach-proven to be very productive in first-principles electronic structure of materials with strong electron correlations. This important book: -- Summarizes the latest developments of electronic structure methods for correlated materials -- Describes each key method from the simplest approximation to the latest developments -- Presents specific topics not often addressed in existing literature Downfolding Methods in Many-Electron Theory is an invaluable resource for researchers and practitioners working in electronic structure in condensed matter physics. The book presents the topic at a level also appropriate for graduate students.

Book Synopsis Variational Methods in Electron-Atom Scattering Theory by : R. K. Nesbet
Download or read book Variational Methods in Electron-Atom Scattering Theory written by R. K. Nesbet and published by Springer. This book was released on 1980-07 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation of scattering phenomena is a major theme of modern physics. A scattered particle provides a dynamical probe of the target system. The practical problem of interest here is the scattering of a low energy electron by an N-electron atom. It has been difficult in this area of study to achieve theoretical results that are even qualitatively correct, yet quantitative accuracy is often needed as an adjunct to experiment. The present book describes a quantitative theoretical method, or class of methods, that has been applied effectively to this problem. Quantum mechanical theory relevant to the scattering of an electron by an N-electron atom, which may gain or lose energy in the process, is summarized in Chapter 1. The variational theory itself is presented in Chapter 2, both as currently used and in forms that may facilitate future applications. The theory of multichannel resonance and threshold effects, which provide a rich structure to observed electron-atom scattering data, is presented in Chapter 3. Practical details of the computational implementation of the variational theory are given in Chapter 4. Chapters 5 and 6 summarize recent appli cations of the variational theory to problems of experimental interest, with many examples of the successful interpretation of complex structural fea tures observed in scattering experiments, and of the quantitative prediction of details of electron-atom scattering phenomena.

Book Synopsis Open Issues in Core Collapse Supernova Theory by : Anthony Mezzacappa
Download or read book Open Issues in Core Collapse Supernova Theory written by Anthony Mezzacappa and published by World Scientific. This book was released on 2005-12-01 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efforts to uncover the explosion mechanism of core collapse supernovae and to understand all of their associated phenomena have been ongoing for nearly four decades. Despite this, our theoretical understanding of these cosmic events remains limited; two- and three-dimensional modeling of these events is in its infancy. Most of the modeling efforts over the past four decades have, by necessity, been constrained to spherical symmetry, with the first two-dimensional, albeit simplified, models appearing only during the last decade. Simulations to understand the complex interplay between the turbulent stellar core fluid flow, its magnetic fields, the neutrinos produced in and emanating from the proto-neutron star, the stellar core rotation, and the strong gravitational fields have yet to be performed. Only subsets of these fundamental ingredients have been included in the models thus far, often with approximation. The purpose of this volume is to identify the outstanding issues that remain in order to come to a complete understanding of these important astrophysical events. As the book focuses on open issues rather than the current state of the art in the field — although the latter will certainly be discussed — it will remain relevant for some time. Contents:Fundamental Issues in Radiation MagnetohydrodynamicsThe Core Collapse Supernova MechanismNeutrino MixingNeutrino InteractionsThe Equation of StateNucleosynthesis and Light Curves Readership: Graduate students and researchers in astrophysics, especially in the study of core collapse supernovae.

Book Synopsis Ab Initio Studies on Superconductivity in Alkali-Doped Fullerides by : Yusuke Nomura
Download or read book Ab Initio Studies on Superconductivity in Alkali-Doped Fullerides written by Yusuke Nomura and published by Springer. This book was released on 2016-08-03 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers high-transition temperature (Tc) s-wave superconductivity and the neighboring Mott insulating phase in alkali-doped fullerides. The author presents (1) a unified theoretical description of the phase diagram and (2) a nonempirical calculation of Tc. For these purposes, the author employs an extension of the DFT+DMFT (density-functional theory + dynamical mean-field theory). He constructs a realistic electron–phonon-coupled Hamiltonian with a newly formulated downfolding method. The Hamiltonian is analyzed by means of the extended DMFT. A notable aspect of the approach is that it requires only the crystal structure as a priori knowledge. Remarkably, the nonempirical calculation achieves for the first time a quantitative reproduction of the experimental phase diagram including the superconductivity and the Mott phase. The calculated Tc agrees well with the experimental data, with the difference within 10 K. The book provides details of the computational scheme, which can also be applied to other superconductors and other phonon-related topics. The author clearly describes a superconducting mechanism where the Coulomb and electron–phonon interactions show an unusual cooperation in the superconductivity thanks to the Jahn–Teller nature of the phonons.

Book Synopsis Many-Electron Approaches in Physics, Chemistry and Mathematics by : Volker Bach
Download or read book Many-Electron Approaches in Physics, Chemistry and Mathematics written by Volker Bach and published by Springer. This book was released on 2014-07-01 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
