This book is a wide-ranging survey of the physics of out-of-equilibrium systems of correlated electrons, ranging from the theoretical, to the numerical, computational and experimental aspects. It starts from basic approaches to non-equilibrium physics, such as the mean-field approach, then proceeds to more advanced methods, such as dynamical mean-field theory and master equation approaches. Lastly, it offers a comprehensive overview of the latest advances in experimental investigations of complex quantum materials by means of ultrafast spectroscopy.
The continuous evolution and development of experimental techniques is at the basis of any fundamental achievement in modern physics. Strongly correlated systems (SCS), more than any other, need to be investigated through the greatest variety of experimental techniques in order to unveil and crosscheck the numerous and puzzling anomalous behaviors characterizing them. The study of SCS fostered the improvement of many old experimental techniques, but also the advent of many new ones just invented in order to analyze the complex behaviors of these systems. Many novel materials, with functional properties emerging from macroscopic quantum behaviors at the frontier of modern research in physics,...
Ruthenate materials have come into focus recently because of their very interesting magnetic and superconducting properties. From the first international conference on this topic, the present volume has emerged as a first coherent account of the considerable body of work, both theoretical and experimental, gathered in this field within a short time span. The book has been written in the form of a set of lectures and tutorial reviews with the aim of providing the research community with both a comprehensive and modern source of reference and a tutorial introduction for postgraduate students and nonspecialists working in related areas.
Analyzing the literature on art from the fifteenth and sixteenth centuries, The Spiritual Language of Art explores the complex relationship between visual art and spiritual experiences during the Italian Renaissance. Though scholarly research on these writings has predominantly focused on the influence of classical literature, this study reveals that Renaissance authors consistently discussed art using terms, concepts and metaphors derived from spiritual literature. By examining these texts in the light of medieval sources, greater insight is gained on the spiritual nature of the artist’s process and the reception of art. Offering a close re-readings of many important writers (Alberti, Leonardo, Vasari, etc.), this study deepens our understanding of attitudes toward art and spirituality in the Italian Renaissance.
In the late fifteenth century, votive panel paintings, or tavolette votive, began to accumulate around reliquary shrines and miracle-working images throughout Italy. Although often dismissed as popular art of little aesthetic consequence, more than 1,500 panels from the fifteenth and sixteenth centuries are extant, a testimony to their ubiquity and importance in religious practice. Humble in both their materiality and style, they represent donors in prayer and supplicants petitioning a saint at a dramatic moment of crisis. In this book, Fredrika H. Jacobs traces the origins and development of the use of votive panels in this period. She examines the form, context and functional value of votive panels, and considers how they created meaning for the person who dedicated them as well as how they accrued meaning in relationship to other images and objects within a sacred space activated by practices of cultic culture.
This book presents the state-of-the-art in simulation on supercomputers. Leading researchers present results achieved on systems of the High Performance Computing Center Stuttgart (HLRS) for the year 2010. The reports cover all fields of computational science and engineering, ranging from CFD to computational physics and chemistry to computer science, with a special emphasis on industrially relevant applications. Presenting results for both vector systems and microprocessor-based systems, the book makes it possible to compare the performance levels and usability of various architectures. As HLRS operates the largest NEC SX-8 vector system in the world, this book gives an excellent insight into the potential of vector systems, covering the main methods in high performance computing. Its outstanding results in achieving the highest performance for production codes are of particular interest for both scientists and engineers. The book includes a wealth of color illustrations and tables.
The articles in this exceptional book contain regular papers, extended papers and reviews, and thus vary in length and are useful for all kinds of audience. They describe, as the book's name suggests, HTSC models and methodologies. Physical models (like extended BCS model, bipolaron model, spin bag model, RVB (resonating valence bond) model, preformed Cooper pairs and antiferromagnetic spin fluctuation (AFSF) based models, stripe phase, paired cluster (spin glass (SG) frustration based) model, Kamimura-Suwa (Hund's coupling mechanism based) model, electron- plasmon interaction, electron- phonon interaction, etc.), theoretical methods (methodologies) (like generalised BCS-Migdal-Eliashberg theory, Hubbard model, t-J model, t-t'-U model, Hubbard-Holstein model, Fermi-, non Fermi- and marginal Fermi- liquid concepts, generalised Hartree-Fock formalism, etc.) and, experimental status and methodologies are all described there. For comparison with cuprates, fullerenes, ruthenates, organic-, non Cu-containing oxide-and conventional (elemental, A15)- superconductors, molecular crystals, nickelates, manganites, borides etc. are also discussed.
This book provides course material in theoretical physics intended for undergraduate and graduate students specializing in condensed matter. The book derives from teaching activity, offering readable and mathematical treatments explained in sufficient detail to be followed easily. The main emphasis is always on the physical meaning and applicability of the results. Many examples are provided for illustration; these also serve as worked problems. Discussion extends to atomic physics, relativistic quantum mechanics, elementary QED, electron spectroscopy, nonlinear optics, and various aspects of the many-body problem. Methods such as group representation theory, Green’s functions, the Keldysh formalism and recursion techniques were also imparted.
Contains articles written by leading experts in the field of condensed matter physics. The book is intended to give a status report of hot topics of solid state physics.
Cosimo dei Medici stabilized ducal finances, secured his borders, doubled his territory, attracted scholars and artists to his court, academy, and universities, and dissipated fractious Florentine politics. These triumphs were far from a foregone conclusion, as Gregory Murry shows in this study of how Cosimo crafted his image as a sacral monarch.
