Summary:

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.
