Dimerized Quantum Magnets

This book features the nature of spin dimer systems, a class of gapped quantum magnets. Spin dimer systems host prototypical quantum phase transitions (QPTs) driven by applied magnetic field and pressure, as well as profound magnetic excitations identical to Nambu–Goldstone and Higgs modes. The book focuses on the physics of QPTs, their criticality, and magnetic excitations in specific materials, and comprehensively reviews up-to-date research in this field. The book begins with fundamental reviews of spin dimer systems, their excitations, and QPTs, and subsequently delves into individual advanced topics in materials. All contributed chapters feature topical reviews by recognized experts in the field. The book is a valuable resource for graduate students and non-expert readers interested in but not necessarily familiar with the subject. The cutting-edge content enables readers to quickly catch up with the latest research in this exciting area.
