Giorgio Parisi – författare

The important changes quantum mechanics has undergone in recent years are reflected in this approach for students. A strong narrative and over 300 worked problems lead the student from experiment, through general principles of the theory, to modern applications. Stepping through results allows students to gain a thorough understanding. Starting with basic quantum mechanics, the book moves on to more advanced theory, followed by applications, perturbation methods and special fields, and ending with developments in the field. Historical, mathematical and philosophical boxes guide the student through the theory. Unique to this textbook are chapters on measurement and quantum optics, both at the forefront of current research. Advanced undergraduate and graduate students will benefit from this perspective on the fundamental physical paradigm and its applications. Online resources including solutions to selected problems, and 200 figures, with colour versions of some figures, are available at www.cambridge.org/Auletta.

Based on the long-running Probability Theory course at the Sapienza University of Rome, this book offers a fresh and in-depth approach to probability and statistics, while remaining intuitive and accessible in style. The fundamentals of probability theory are elegantly presented, supported by numerous examples and illustrations, and modern applications are later introduced giving readers an appreciation of current research topics. The text covers distribution functions, statistical inference and data analysis, and more advanced methods including Markov chains and Poisson processes, widely used in dynamical systems and data science research. The concluding section, 'Entropy, Probability and Statistical Mechanics' unites key concepts from the text with the authors' impressive research experience, to provide a clear illustration of these powerful statistical tools in action. Ideal for students and researchers in the quantitative sciences this book provides an authoritative account of probability theory, written by leading researchers in the field.

This pedagogical and self-contained text describes the modern mean field theory of simple structural glasses. The book begins with a thorough explanation of infinite-dimensional models in statistical physics, before reviewing the key elements of the thermodynamic theory of liquids and the dynamical properties of liquids and glasses. The central feature of the mean field theory of disordered systems, the existence of a large multiplicity of metastable states, is then introduced. The replica method is then covered, before the final chapters describe important, advanced topics such as Gardner transitions, complexity, packing spheres in large dimensions, the jamming transition, and the rheology of glass. Presenting the theory in a clear and pedagogical style, this is an excellent resource for researchers and graduate students working in condensed matter physics and statistical mechanics.

Ein eindrucksvoller und persönlicher Einblick in Welt der Physik und den Kopf eines Genies. »Der Nobelpreis für Giorgio Parisi ehrt einen außergewöhnlichen Wissenschaftler und bestätigt das hohe Niveau der italienischen Schule der theoretischen Physik.« Carlo Rovelli

Giorgio Parisi. Premi Nobel de FísicaResultats experimentals fora de les lleis conegudes, recerques amb descobriments insòlits per als investigadors, llampecs d''intuïcions memorables en física i matemàtiques: aquest és el món esmunyedís que ha estudiat Giorgio Parisi, premi Nobel 2021, al llarg de més de cinquanta anys.Aquest llibre és un viatge a l''extraordinària ment d''un físic prestigiós que, amb vint-i-cinc anys, ja va estar ben a prop del Nobel. Hi repassa els seus estudis pioners sobre partícules elementals i les propietats de determinats aliatges, i sobre fenòmens enigmàtics com les transicions de fase o el vol dels estornells en bandades (¿com es crea l''ordre en moviments de tants individus i tanta complexitat?). I, com a culminació, ens aporta les seves últimes reflexions sobre com sorgeixen les idees i la transcendència de la ciència en la nostra societat.

This volume is a collection of lectures and selected papers by Giorgio Parisi on the subjects of Field Theory (perturbative expansions, nonperturbative phenomena and phase transitions), Disordered Systems (mainly spin glasses) and Computer Simulations (lattice gauge theories).The basic problems discussed in the Field Theory section concern the interplay between perturbation theory and nonperturbative phenomena which are present when one deals with infrared or ultraviolet divergences or with nonconvergent perturbative expansions. The section on Disordered Systems contains a complete discussion about the replica method and its probabilistic interpretation, and also includes a short paper on multifractals. In the Simulations section, there is a series of lectures devoted to the study of quantum chromodynamics and a review paper on simulations in complex systems.The works of Giorgio Parisi have repeatedly displayed a remarkable depth of originality and innovation, and have paved the way for new research in many areas. This personal selection of his lectures and papers, complete with an original introduction by him, undoubtedly serves as a vital reference book for physicists and mathematicians working in these fields.

About sixty years ago, the anomalous magnetic response of certain magnetic alloys drew the attention of theoretical physicists. It soon became clear that understanding these systems, now called spin glasses, would give rise to a new branch of statistical physics. As physical materials, spin glasses were found to be as useless as they were exotic. They have nevertheless been recognized as paradigmatic examples of complex systems with applications to problems as diverse as neural networks, amorphous solids, biological molecules, social and economic interactions, information theory and constraint satisfaction problems.This book presents an encyclopaedic overview of the broad range of these applications. More than 30 contributions are compiled, written by many of the leading researchers who have contributed to these developments over the last few decades. Some timely and cutting-edge applications are also discussed. This collection serves well as an introduction and summary of disordered and glassy systems for advanced undergraduates, graduate students and practitioners interested in the topic.

This book provides a selection of papers of the late Daniel Amit (1938–2007). Daniel Amit was a physicist who spent the last 22 years of his life working on neural network models. He was one of the pioneers in the field. The volume contains 21 papers, from the highly influential 1985 paper on the Hopfield model (published together with Hanoch Gutfreund and Haim Sompolinsky), to his last (unpublished) manuscript. Many of these papers are landmark papers in the field. The book also provides a biography; an introduction on Daniel Amit's scientific career before the Hopfield model; and introductions to each of the included papers, written by their co-authors. This book will be of interest to physicists, computational neuroscientists and neurobiologists.
