Downfolding Methods in Many-Electron Theory

Abstract

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 materialsDescribes each key method from the simplest approximation to the latest developmentsPresents 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.
