"The Mott Metal-Insulator Transition" is a specialized book that delves into the complex topic of the Mott transition, a phenomenon of great significance in solid-state physics. The author, Florian Gebhard, provides a comprehensive analysis of the theoretical concepts that characterize Mott insulators and examines the role of electron correlations in the formation of band gaps for charge carriers. The book is based on the ideas of the renowned physicist Sir Nevill Mott and aims to present both the fundamental theoretical approaches and their validation through model calculations. In particular, the Hubbard model is highlighted as a suitable tool for describing the Mott transition with minimal variable parameters. By discussing exact solutions and their application to approximate theories, the book seeks to foster a deeper understanding of correlated electron systems. This book is a valuable resource for students and professionals who wish to engage with the challenges and open questions in the field of metal-insulator transitions.
