Sommario/riassunto |
|
This book presents the induced representation method, a powerful technique in quantum mechanics with applications in condensed matter physics. After introducing the key concepts in group theory and representation theory necessary to understate the technique, the author goes on to explore applications in electron structure theory, namely: basis sets in clusters, normal vibrations, selection rules, two-electron wavefunctions, and space-group representations. This technique allows the simplification of standard techniques for the analysis of molecular orbitals and normal vibrations of molecules. A space group approach to the wavefunction of a Cooper pair based on the Anderson ansatz and Mackey-Bradley theorem is developed, and several applications are considered, namely group-theoretical nodes, non-symmorphic groups, and unification of the group theoretical and topological approaches to the structure of Cooper pairs in unconventional superconductors. |

Ces rapports présentent les travaux de la Conférence Européenne des Ministres des Transports et ses relations avec d’autres Organisations internationales. En même temps qu’il reprend les études sectorielles menées par la Conférence, le rapport contient une analyse globale de la situation des transports dans l’aire de la CEMT pour l’année en revue. |
