AdS CFT Duality User Guide This book describes applications of the AdS CFT duality to the real world. The AdS CFT duality is an idea that originated from string theory and is a powerful tool for analyzing strongly coupled gauge theories using classical gravitational theories. In recent years it has been shown that one prediction of AdS CFT is indeed close to the experimental result of the real quark gluon plasma. Since then the AdS CFT duality has been applied to various fields of physics; examples are QCD nuclear physics condensed matter physics and nonequilibrium physics. The aim of this book is to provide background materials such as string theory black holes nuclear physics condensed matter physics and nonequilibrium physics as well as key applications of the AdS CFT duality in a single volume. The emphasis throughout the book is on a pedagogical and intuitive approach focusing on the underlying physical concepts. It also includes step by step computations for important results which are useful for beginners. This book will be a valuable reference work for graduate students and researchers in particle physics general relativity nuclear physics nonequilibrium physics and condensed matter physics.
