Materials -- Conclusion -- Appendices. 330 $aThis book deals with the study of superconductivity in systems with coexisting wide and narrow bands. It has been previously suggested that superconductivity can be enhanced in systems with coexisting wide and narrow bands when the Fermi level is near the narrow band edge. In this book, the authors study two problems concerning this mechanism in order to: (a) provide a systematic understanding of the role of strong electron correlation effects, and (b) propose a realistic candidate material which meets the ideal criteria for high-Tc superconductivity. Regarding the role of strong correlation effects, the FLEX+DMFT method is adopted. Based on systematic calculations, the pairing mechanism is found to be indeed valid even when the strong correlation effect is considered within the formalism. In the second half of the book, the authors propose a feasible candidate material by introducing the concept of the ?hidden ladder? electronic structure, arising from the combination of the bilayer lattice structure and the anisotropic orbitals of the electrons. As such, the book contributes a valuable theoretical guiding principle for seeking unknown high-Tc superconductors. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aSuperconductivity 606 $aSuperconductors 606 $aSolid state physics 606 $aLow temperature physics 606 $aLow temperatures 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 $aLow Temperature Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P25130 615 0$aSuperconductivity. 615 0$aSuperconductors. 615 0$aSolid state physics. 615 0$aLow temperature physics. 615 0$aLow temperatures. 615 14$aStrongly Correlated Systems, Superconductivity. 615 24$aSolid State Physics. 615 24$aLow Temperature Physics. 676 $a537.623 700 $aOgura$b Daisuke$4aut$4http://id.loc.gov/vocabulary/relators/aut$0839057 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910350220403321 996 $aTheoretical Study of Electron Correlation Driven Superconductivity in Systems with Coexisting Wide and Narrow Bands$91873842 997 $aUNINA
