The objective of the book is twofold. First, it gives a detailed presentation of the dynamic spin-fluctuation theory that takes into account both local and long-wave spin fluctuations with any frequency. The authors provide a detailed explanation of the fundamental role of quantum spin fluctuations in the mechanism of metallic magnetism and illustrate the theory with concrete examples. The second objective of the book is to give an accurate and self-contained presentation of many-body techniques such as the functional integral method and Green's functions, via a number of worked examples. These computational methods are of great use to solid state physicists working in a range of specialties. The book is intended primarily for researchers, but can also be used as textbook. The introductory chapters offer clear and complete derivations of the fundamentals, which makes the presentation self-contained. The main text is followed by a number of well-organized appendices that contain a detailed presentation of the necessary many-body techniques and computational methods. The book also includes a list of symbols and detailed index. This volume will be of interest to a wide range of physicists interested in magnetism and solid state physics in general, both theoreticians and experimentalists. 606 $aMagnetism 606 $aMagnetic materials 606 $aMetals 606 $aElectrochemistry 606 $aQuantum computers 606 $aSpintronics 606 $aSolid state physics 606 $aMagnetism, Magnetic Materials$3https://scigraph.springernature.com/ontologies/product-market-codes/P25129 606 $aMetallic Materials$3https://scigraph.springernature.com/ontologies/product-market-codes/Z16000 606 $aElectrochemistry$3https://scigraph.springernature.com/ontologies/product-market-codes/C21010 606 $aQuantum Information Technology, Spintronics$3https://scigraph.springernature.com/ontologies/product-market-codes/P31070 606 $aSolid State Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P25013 615 0$aMagnetism. 615 0$aMagnetic materials. 615 0$aMetals. 615 0$aElectrochemistry. 615 0$aQuantum computers. 615 0$aSpintronics. 615 0$aSolid state physics. 615 14$aMagnetism, Magnetic Materials. 615 24$aMetallic Materials. 615 24$aElectrochemistry. 615 24$aQuantum Information Technology, Spintronics. 615 24$aSolid State Physics. 676 $a538 700 $aMelnikov$b Nikolai B$4aut$4http://id.loc.gov/vocabulary/relators/aut$0833974 702 $aReser$b Boris I$4aut$4http://id.loc.gov/vocabulary/relators/aut 906 $aBOOK 912 $a9910300160803321 996 $aDynamic Spin-Fluctuation Theory of Metallic Magnetism$92508258 997 $aUNINA
