Theoretical Tools for Spin Models in Magnetic Systems

Theoretical Tools for Spin Models in Magnetic SystemsThis 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 Greens function. Some important areas of interest in magnetism today are spin liquids and magnon topological insulators, both of which are discussed in the book.
