"This book's aim is to provide training in the main subjects of quantum many-body theories, in order to understand and predict the properties of macroscopic matter arising from the interactions between its elementary constituents, with an interdisciplinary perspective, and from the development of fundamental theoretical techniques to practical applications. [...] This book will be valuable for graduate students and researchers interested in the study of quantum many-body systems in particle, nuclear, molecular, atomic or condensed matter physics, or in quantum optics and quantum field theory."
