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.

This book contains a detailed and self-contained presentation of
the replica theory of infinite range spin glasses. The authors also
explain recent theoretical developments, paying particular
attention to new applications in the study of optimization theory
and neural networks. About two-thirds of the book are a collection
of the most interesting and pedagogical articles on the subject.
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.
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.

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.
From the 2021 Nobel Prize winner in Physics, a remarkable journey
into the practice of groundbreaking science 'Giorgio Parisi is
renowned for his scientific creativity, originality, and power. In
this exhilarating little book, he shows his human side, too. By its
end, readers will feel they've made a charming, witty new friend'
Frank Wilczek The world is shaped by complexity. In this
enlightening book, Nobel Prize winner Giorgio Parisi guides us
through his unorthodox yet exhilarating work to show us how. It all
starts with investigating the principles of physics by observing
the sophisticated flight patterns of starlings. Studying the
movements of these birds, he has realized, proves an illuminating
way into understanding complex systems of all kinds - collections
of everything from atoms to planets to other animals like
ourselves. Along the way, Parisi reflects on the lessons he's taken
from a life in pursuit of scientific truth: the importance of
serendipity to the discovery of new ideas, the surprising kinship
between physics and other fields of study and the value of science
to a thriving society. In so doing, he removes the practice of
science from the confines of the laboratory and into the real
world. Complexity is all around us - from climate to finance to
biology, it offers a unique way of finding order in chaos. Part
elegant scientific treatise, part thrilling intellectual journey,
In a Flight of Starlings is an invitation to find wonder in the
world around us.
