The content is divided into three parts, the first of which introduces readers to perturbation theory. It begins with the simplest examples?hydrogen and oxygen molecules?based on their effective Hamiltonians, and looks into basic properties of electrons in solids from the perspective of localized and itinerant limits. Readers will also learn about basic theoretical methods such as the linear response theory and Green functions. The second part focuses on mean-field theory for itinerant electrons, e.g. the Fermi liquid theory and superconductivity. Coulomb repulsion among electrons is addressed in the context of high-Tc superconductivity in cuprates and iron pnictides. A recent discovery concerning hydride superconductors is also briefly reviewed. In turn, the third part highlights quantum fluctuation effects beyond the mean-field picture. Discussing the dramatic renormalization effect in the Kondo physics, it provides a clear understanding of nonperturbative interaction effects. Further it introduces readers to fractionally charged quasi-particles in one and two dimensions. The last chapter addresses the dynamical mean field theory (DMFT). The book is based on the author?s long years of experience as a lecturer and researcher. It also includes reviews of recent focus topics in condensed matter physics, enabling readers to not only grasp conventional condensed matter theories but also to catch up on the latest developments in the field. 410 0$aLecture Notes in Physics,$x0075-8450 ;$v934 606 $aSuperconductivity 606 $aSuperconductors 606 $aSolid state physics 606 $aMagnetism 606 $aMagnetic materials 606 $aLow temperature physics 606 $aLow temperatures 606 $aStatistical physics 606 $aStrongly Correlated Systems, Superconductivity$3https://scigraph.springernature.com/ontologies/product-market-codes/P25064 606 $aSolid State Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P25013 606 $aMagnetism, Magnetic Materials$3https://scigraph.springernature.com/ontologies/product-market-codes/P25129 606 $aLow Temperature Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P25130 606 $aStatistical Physics and Dynamical Systems$3https://scigraph.springernature.com/ontologies/product-market-codes/P19090 615 0$aSuperconductivity. 615 0$aSuperconductors. 615 0$aSolid state physics. 615 0$aMagnetism. 615 0$aMagnetic materials. 615 0$aLow temperature physics. 615 0$aLow temperatures. 615 0$aStatistical physics. 615 14$aStrongly Correlated Systems, Superconductivity. 615 24$aSolid State Physics. 615 24$aMagnetism, Magnetic Materials. 615 24$aLow Temperature Physics. 615 24$aStatistical Physics and Dynamical Systems. 676 $a530.144 700 $aKuramoto$b Yoshio$4aut$4http://id.loc.gov/vocabulary/relators/aut$0859286 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910380737903321 996 $aQuantum Many-Body Physics$91917826 997 $aUNINA
