Getting Started on Time-Resolved Molecular Spectroscopy / Jeffrey A. Cina 

Public ISBD Titre : Getting Started on Time-Resolved Molecular Spectroscopy Type de document : texte imprimé Auteurs : Jeffrey A. Cina, Auteur Editeur : Oxford : Oxford University Press Année de publication : 2022 Collection : Oxford graduate texts Importance : 160 P Présentation : ILL Format : 25.02 x 1.45 x 17.91 cm ISBN/ISSN/EAN : 978-0-19-959031-5 Langues : Anglais (eng) Langues originales : Anglais (eng) Mots-clés : Time-Resolved Spectroscopy Molecular Dynamics Ultrafast Spectroscopy Quantum Mechanics Femtosecond Lasers Wave Packets Nonlinear Spectroscopy Photoexcitation. Résumé : this textbook provides an overview of the basics of ultrafast molecular spectroscopy starting from time-dependent quantum mechanical perturbation theory in Hilbert space. It emphasizes the dynamics of nuclear and electronic motion, initiated and monitored by femtosecond laser pulses, which underlie the generation of nonlinear optical signals and inform their interpretation. Topics include short-pulse electronic absorption, the molecular adiabatic approximation, transient-absorption spectroscopy, vibrational adiabaticity during conformational change, femtosecond stimulated Raman spectroscopy, multi-dimensional electronic spectroscopy and wave-packet interferometry, and two-dimensional wave-packet interferometry of electronic excitation-transfer systems. The treatment is based on time-dependent quantum mechanics as it is presented in graduate-level quantum mechanics courses. It is designed to be accessible to beginning practitioners of ultrafast spectroscopy and is meant to serve as a bridge to more advanced treatises and research publications. Numerous exercises are embedded in the text to explore and expand upon the physical ideas encountered in this important research field.

Quantum liquids / A.J. Leggett

Public ISBD Titre : Quantum liquids : Bose condensation and Cooper pairing in condensed-matter systems Type de document : texte imprimé Auteurs : A.J. Leggett, Auteur Editeur : Oxford : Oxford University Press Année de publication : 2006 Collection : Oxford graduate texts Importance : 1 vol. (XV-388 p.) Présentation : ill. Format : 26 cm ISBN/ISSN/EAN : 978-0-19-852643-8 Note générale : Bibliogr. p. [373]-379- Index Langues : Anglais (eng) Mots-clés : Bose-Einstein condensation  Helium  Quantum liquids  Superconductivity Index. décimale : 530.42 LEG Résumé : Starting from first principles, this book introduces the closely related phenomena of Bose condensation and Cooper pairing, in which a very large number of single particles or pairs of particles are forced to behave in exactly the same way, and explores their consequences in condensed matter systems. Eschewing advanced formal methods, the author uses simple concepts and arguments to account for the various qualitatively new phenomena which occur in Bose-condensed and Cooper-paired systems, including but not limited to the spectacular macroscopic phenomena of superconductivity and superfluidity. The physical systems discussed include liquid 4-He, the BEC alkali gases, "classical" superconductors, superfluid 3-He, "exotic" superconductors and the recently stabilized Fermi alkali gases. The book should be accessible to beginning graduate students in physics or advanced undergraduates. Note de contenu : 1. Introduction:quantum statistics,Bose-Einstein condensation and Cooper pairing. ; 2. Bose-Einstein condensation:its definition,origin,occurrence and consequences. ; 3. Liquid 4-He. ; 4. The Bose alkali gases. ; 5. Classical superconductivity. ; 6. Superfluid 3-He ; 7. Cuprate superconductivity. ; 8. Miscellaneous topics.
