This book provides an overview of the field of quantum fluids. It presents analogies and differences between polariton and atomic quantum fluids and explains a new type of quantum fluid with specific characteristics.

This book summarizes current research on exciton polaritons in microcavities: interactions, fast dynamics, spin-dependent phenomena, temporal and spatial coherence, condensation under non-equilibrium conditions, related collective quantum phenomena and more.

Electronic structure and physical properties of strongly correlated materials containing elements with partially filled 3d, 4d, 4f and 5f electronic shells is analyzed by Dynamical Mean-Field Theory (DMFT). DMFT is the most universal and effective tool used for the theoretical investigation of electronic states with strong correlation effects. In the present book the basics of the method are given and its application to various material classes is shown. The book is aimed at a broad readership: theoretical physicists and experimentalists studying strongly correlated systems. It also serves as a handbook for students and all those who want to be acquainted with the fast developing field of condensed matter physics.

This book describes theoretical aspects of metallic magnetism from metals to disordered alloys to amorphous alloys both at the ground state and at finite temperatures. Explores the topic via spin-fluctuation theories based on the functional integral method.

The first of its kind on the topic, this book presents a unified description of topological insulators in one, two and three dimensions based on the modified Dirac equation. Discusses topological invariants and their applications to a variety of systems.
