Theoretical Tools for Spin Models in Magnetic Systems

This book is dedicated to the study of theoretical tools in spin models in magnetism. It presents the basic tools to treat spin models in magnetic systems such as: spin waves, Schwinger bosons formalism, Self-consistent harmonic approximation, Kubo theory, Perturbation theory using Green's function. Some important areas of interest in magnetism today are spin liquids and magnon topological insulators, both of which are discussed in the book.
