In this sweeping history, leading Haitian intellectual Jean Casimir argues that the story of Haiti should not begin with the usual image of Saint-Domingue as the richest colony of the eighteenth century. Rather, it begins with a reconstruction of how individuals from Africa, in the midst of the golden age of imperialism, created a sovereign society based on political imagination and a radical rejection of the colonial order, persisting even through the U.S. occupation in 1915. The Haitians also critically retheorizes the very nature of slavery, colonialism, and sovereignty. Here, Casimir centers the perspectives of Haiti's moun andeyo—the largely African-descended rural peasantry. Asking how these systematically marginalized and silenced people survived in the face of almost complete political disenfranchisement, Casimir identifies what he calls a counter-plantation system. Derived from Caribbean political and cultural practices, the counter-plantation encompassed consistent reliance on small-scale landholding. Casimir shows how lakou, small plots of land often inhabited by generations of the same family, were and continue to be sites of resistance even in the face of structural disadvantages originating in colonial times, some of which continue to be maintained by the Haitian government with support from outside powers.
The aim of this textbook is to provide an overview of nanophotonics, a discipline which was developed around the turn of the millennium. This unique and rapidly evolving subject area is the result of a collaboration between various scientific communities working on different aspects of light-matter interaction at the nanoscale. These include near-field optics and super-resolution microscopy, photonic crystals, diffractive optics, plasmonics, optoelectronics, synthesis of metallic and semiconductor nanoparticles, two-dimensional materials, and metamaterials. The book is aimed at graduate students with a background in physics, electrical engineering, material science, or chemistry, as well as lecturers and researchers working within these fields.
This book provides an extensive survey of all the physics necessary to understand the current developments in the field of fundamental cosmology, as well as an overview of the observational data and methods. It will help students to get into research by providing definitions and main techniques and ideas discussed today. The book is divided into three parts. Part 1 summarises the fundamentals in theoretical physics needed in cosmology (general relativity, field theory, particle physics). Part 2 describes the standard model of cosmology and includes cosmological solutions of Einstein equations, the hot big bang model, cosmological perturbation theory, cosmic microwave background anisotropies, lensing and evidence for dark matter, and inflation. Part 3 describes extensions of this model and opens up current research in the field: scalar-tensor theories, supersymmetry, the cosmological constant problem and acceleration of the universe, topology of the universe, grand unification and baryogenesis, topological defects and phase transitions, string inspired cosmology including branes and the latest developments. The book provides details of all derivations and leads the student up to the level of research articles.
Although the Middle Ages saw brilliant achievements in the diverse nations of East Central Europe, this period has been almost totally neglected in Western historical scholarship. East Central Europe in the Middle Ages provides a much-needed overview of the history of the region from the time when the present nationalities established their state structures and adopted Christianity up to the Ottoman conquest. Jean Sedlar’s excellent synthesis clarifies what was going on in Europe between the Elbe and the Ukraine during the Middle Ages, making available for the first time in a single volume information necessary to a fuller understanding of the early history of present-day Poland, the Czech Republic, Slovakia, Hungary, Romania, Bulgaria, Albania, and the former Yugoslavia. Sedlar writes clearly and fluently, drawing upon publications in numerous languages to craft a masterful study that is accessible and valuable to the general reader and the expert alike. The book is organized thematically; within this framework Sedlar has sought to integrate nationalities and to draw comparisons. Topics covered include early migrations, state formation, monarchies, classes (nobles, landholders, peasants, herders, serfs, and slaves), towns, religion, war, governments, laws and justice, commerce and money, foreign affairs, ethnicity and nationalism, languages and literature, and education and literacy. After the Middle Ages these nations were subsumed by the Ottoman, Habsburg, Russian, and Prussian-German empires. This loss of independence means that their history prior to foreign conquest has acquired exceptional importance in today’s national consciousness, and the medieval period remains a major point of reference and a source of national pride and ethnic identity. This book is a substantial and timely contribution to our knowledge of the history of East Central Europe.
This book uses the hypoelliptic Laplacian to evaluate semisimple orbital integrals in a formalism that unifies index theory and the trace formula. The hypoelliptic Laplacian is a family of operators that is supposed to interpolate between the ordinary Laplacian and the geodesic flow. It is essentially the weighted sum of a harmonic oscillator along the fiber of the tangent bundle, and of the generator of the geodesic flow. In this book, semisimple orbital integrals associated with the heat kernel of the Casimir operator are shown to be invariant under a suitable hypoelliptic deformation, which is constructed using the Dirac operator of Kostant. Their explicit evaluation is obtained by localization on geodesics in the symmetric space, in a formula closely related to the Atiyah-Bott fixed point formulas. Orbital integrals associated with the wave kernel are also computed. Estimates on the hypoelliptic heat kernel play a key role in the proofs, and are obtained by combining analytic, geometric, and probabilistic techniques. Analytic techniques emphasize the wavelike aspects of the hypoelliptic heat kernel, while geometrical considerations are needed to obtain proper control of the hypoelliptic heat kernel, especially in the localization process near the geodesics. Probabilistic techniques are especially relevant, because underlying the hypoelliptic deformation is a deformation of dynamical systems on the symmetric space, which interpolates between Brownian motion and the geodesic flow. The Malliavin calculus is used at critical stages of the proof.
The aim of this book is twofold. On the one hand, it gives a quick, self-contained introduction to Poisson geometry and related subjects. On the other hand, it presents a comprehensive treatment of the normal form problem in Poisson geometry. Even when it comes to classical results, the book gives new insights. It contains results obtained over the past 10 years which are not available in other books.
Bridging the gap between traditional books on quantum and statistical physics, this series is an ideal introductory course for students who are looking for an alternative approach to the traditional academic treatment.This pedagogical approach relies heavily on scientific or technological applications from a wide range of fields. For every new concept introduced, an application is given to connect the theoretical results to a real-life situation. Each volume features in-text exercises and detailed solutions, with easy-to-understand applications.This third volume covers several basic and more advanced subjects about transitions in quantum and statistical physics. Part I describes how the quantum statistics of fermions and bosons differ and under what condition they can merge into the classical-particle-statistics framework seen in Volume 2. This section also describes the fundamentals of conductors, semiconductors, superconductors, superfluids and Bose-Einstein condensates. Part II introduces time-dependent transitions between quantum states. The time evolution of a simple two-level model gives the minimum background necessary to understand the principles behind lasers and their numerous applications. Time-dependent perturbation theory is also covered, as well as standard approaches to the scattering of massive particles. A semi-classical treatment of electromagnetic field-matter interaction is described with illustrations taken from a variety of processes such as phonon scattering, charge distribution or spin densities. The third and last part of the book gives a brief overview of quantum electrodynamics with applications to photon absorption or emission spectroscopies and a range of scattering regimes. There follows a short introduction to the role of multiphoton processes in quantum entanglement based experiments.
There is no temperature below absolute zero, and, in fact, zero itself is impossible to reach. The quest to reach it has lured scientists for several centuries revealing interesting and unexpected phenomena along the way. Atoms move more slowly at low temperatures, but matter at bareLy above absolute zero is not immobile or even necessarily frozen. Among the most peculiar of matter's strange behaviors is superconductivity3/4simply described as electric current without resistance3/4discovered in 1911. With the 1986 discovery that, contrary to previous expectations, superconductivity was possible at temperatures well above absolute zero, research into practical applications has flourished. Superconductivity has turned out to be a fruitful arena for developments in condensed matter physics, which have proved applicable in particle physics and cosmology as well. Cold Wars tells the history of superconductivity, providing perspective on the development of the field and its relationship with the rest of physics and the history of our time. The authors provide a rare look at the scientists and their research, mostly little known beyond a small coterie of specialists. Superconductivity provides an excellent example of the evolution of physics in the twentieth century: the science itself, its epistemological foundations, and its social context. Cold Wars will be of equal interest to students of physics and the history of science and technology, and general readers interested in story behind this remarkable phenomenon.
Adapted for television in France, the fourth of the Nicolas Le Floch mysteries sees the protagonist accused of murdering a socialite - with whom he was about to end a stormy affair. 'Parot succeeds brilliantly in his reconstruction of pre-revolutionary Paris' The Times Paris, 1774. Commissioner Le Floch's stormy love affair with socialite Julie de Lasterieux has run its course. But before Nicolas can formally end the relationship, Julie is found murdered in her bed, a victim of poisoning. For now, he retains the confidence of even the King, who sends him on a secret intelligence mission. But a plot is afoot to implicate Nicolas in Julie's death, and he is soon fighting to uncover the perpetrators and clear his name.
This book reviews the construction of elementary systems living in de Sitter (dS) spacetime, in both the classical and quantum senses. Field theories on dS spacetime are among the most studied mathematical models of the Universe, whether for its earlier period (inflationary phase) or for its current phase of expansion acceleration (dark energy or cosmological constant). Classical elementary systems are Hamiltonian phase spaces, which are associated with co-adjoint orbits of the relativity group. On the other hand, quantum elementary systems are associated with (projective) unitary irreducible representations of the (possibly extended) relativity group (or one of its covering). This study emphasizes the conceptual issues arising in the formulation of such systems and discusses known results in a mathematically rigorous way. Particular attention is paid to: “smooth” transition from classical to quantum theory; physical content under vanishing curvature, from the point of view of a local (“tangent”) Minkowskian observer; and thermal interpretation (on the quantum level), in the sense of the Gibbons-Hawking temperature. Such a mathematical construction is of paramount importance to the understanding of the early Universe (due to the critical role that the dS metric plays in the inflationary cosmological scenarii) as well as to the construction of possible models for late-time cosmology (since a small positive cosmological constant or dark energy seems to be required by recent data). In this sense, this book uniquely blends mathematical physics (spacetime symmetry on classical and quantum levels) and theoretical physics (quantization, quantum field theory, and cosmology). Moreover, the level of exposition varies in different parts of the book so that both experts and beginners alike can utilize the book.
The counter-intuitive aspects of quantum physics have been long illustrated by thought experiments, from Einstein's photon box to Schrödinger's cat. These experiments have now become real, with single particles - electrons, atoms, or photons - directly unveiling the strange features of the quantum. State superpositions, entanglement and complementarity define a novel quantum logic which can be harnessed for information processing, raising great hopes for applications. This book describes a class of such thought experiments made real. Juggling with atoms and photons confined in cavities, ions or cold atoms in traps, is here an incentive to shed a new light on the basic concepts of quantum physics. Measurement processes and decoherence at the quantum-classical boundary are highlighted. This volume, which combines theory and experiments, will be of interest to students in quantum physics, teachers seeking illustrations for their lectures and new problem sets, researchers in quantum optics and quantum information.

Introduced as a quantum extension of Maxwell's classical theory, quantum electrodynamics has been the first example of a Quantum Field Theory (QFT). Eventually, QFT has become the framework for the discussion of all fundamental interactions at the microscopic scale except, possibly, gravity. More surprisingly, it has also provided a framework for the understanding of second order phase transitions in statistical mechanics. As this work illustrates, QFT is the natural framework for the discussion of most systems involving an infinite number of degrees of freedom with local couplings. These systems range from cold Bose gases at the condensation temperature (about ten nanokelvin) to conventional phase transitions (from a few degrees to several hundred) and high energy particle physics up to a TeV, altogether more than twenty orders of magnitude in the energy scale. Therefore, this text sets out to present a work in which the strong formal relations between particle physics and the theory of critical phenomena are systematically emphasized. This option explains some of the choices made in the presentation. A formulation in terms of field integrals has been adopted to study the properties of QFT. The language of partition and correlation functions has been used throughout, even in applications of QFT to particle physics. Renormalization and renormalization group properties are systematically discussed. The notion of effective field theory and the emergence of renormalisable theories are described. The consequences for fine tuning and triviality issue are emphasized. This fifth edition has been updated and fully revised, e.g. in particle physics with progress in neutrino physics and the discovery of the Higgs boson. The presentation has been made more homogeneous througout the volume, and emphasis has been put on the notion of effective field theory and discussion of the emergence of renormalisable theories.
This second edition is fully updated, covering in particular new types of coherent states (the so-called Gazeau-Klauder coherent states, nonlinear coherent states, squeezed states, as used now routinely in quantum optics) and various generalizations of wavelets (wavelets on manifolds, curvelets, shearlets, etc.). In addition, it contains a new chapter on coherent state quantization and the related probabilistic aspects. As a survey of the theory of coherent states, wavelets, and some of their generalizations, it emphasizes mathematical principles, subsuming the theories of both wavelets and coherent states into a single analytic structure. The approach allows the user to take a classical-like view of quantum states in physics. Starting from the standard theory of coherent states over Lie groups, the authors generalize the formalism by associating coherent states to group representations that are square integrable over a homogeneous space; a further step allows one to dispense with the group context altogether. In this context, wavelets can be generated from coherent states of the affine group of the real line, and higher-dimensional wavelets arise from coherent states of other groups. The unified background makes transparent an entire range of properties of wavelets and coherent states. Many concrete examples, such as coherent states from semisimple Lie groups, Gazeau-Klauder coherent states, coherent states for the relativity groups, and several kinds of wavelets, are discussed in detail. The book concludes with a palette of potential applications, from the quantum physically oriented, like the quantum-classical transition or the construction of adequate states in quantum information, to the most innovative techniques to be used in data processing. Intended as an introduction to current research for graduate students and others entering the field, the mathematical discussion is self-contained. With its extensive references to the research literature, the first edition of the book is already a proven compendium for physicists and mathematicians active in the field, and with full coverage of the latest theory and results the revised second edition is even more valuable.
Originally published in 1968 this book is an unforgettable portrait of an impoverished orphaned daughter of the Medici, pitchforked at the age of fourteen into her royal destiny and having to bear the rivalry of Diane de Poiters and the description ‘the Florentine shopkeeper’ who nevertheless became one of the most powerful characters in the shaping of sixteenth century Europe.
Scientists have not yet explained the weirdness of quantum physics. The authors, a scientist and a philosopher, now join forces to formulate a new Theory of everything. In simple words and with the help of lively dialogues, they show that infinity does not exist in the world of daily experience, and that timelessness is very real. Step by step, they re-examine the evidence and demonstrate how consciousness is the very essence of our existence. In a world where space, time, speed and randomness are relative, they show that we have free will to evolve within a deterministic order, and they conclude that we are a simple link in a long evolution towards increased consciousness. They claim that a Universal Code of ethics based on a scientific morality will help us settle our differences in a universally acceptable way . Their theory explains the weirdness of quantum physics, it gives us a tool to live happy, ethical and productive lives, and logical solutions to the world's political and existential problems.
The articles in this volume are an outgrowth of a colloquium "Systemes Integrables et Feuilletages," which was held in honor of the sixtieth birthday of Pierre Molino. The topics cover the broad range of mathematical areas which were of keen interest to Molino, namely, integral systems and more generally symplectic geometry and Poisson structures, foliations and Lie transverse structures, transitive structures, and classification problems.
Drawing on fundamental notions from quantum physics, this book uses logic and careful reasoning to prove that God exists—but not in the way most think. Jean Paul Corriveau, who earned degrees in mathematics and computer science, explains how long-held beliefs about God are all wrong. After reading, you’ll know: • God is neither the source of intelligence nor consciousness and not the least involved in life and its evolution. • Nature has no design—and intelligence is a product of evolution. • God is nowhere in the universe, but He is its energy source. • There is no heaven, hell, or afterlife. The author argues that the evolution of nature and life, from the Big Bang onward, is from randomness and luck. There was never an intent. God is the only nonphysical entity, so prayers don’t reach Him. The relationships between God, humans, the universe, and Earth aren’t what the Bible tells us or what people think. Join the author as he explores how we know God exists and what that really means.

This book contains fifteen articles by eminent specialists in the theory of completely integrable systems, bringing together the diverse approaches to classical and quantum integrable systems and covering the principal current research developments.
This book explains, in simple terms, with a minimum of mathematics, why things can appear to be in two places at the same time, why correlations between simultaneous events occurring far apart cannot be explained by local mechanisms, and why, nevertheless, the quantum theory can be understood in terms of matter in motion. No need to worry, as some people do, whether a cat can be both dead and alive, whether the moon is there when nobody looks at it, or whether quantum systems need an observer to acquire definite properties. The author’s inimitable and even humorous style makes the book a pleasure to read while bringing a new clarity to many of the longstanding puzzles of quantum physics.
In 1631, when the Dutch tried to develop plantation agriculture in the Delaware Valley, the Lenape Indians destroyed the colony of Swanendael and killed its residents. The Natives and Dutch quickly negotiated peace, avoiding an extended war through diplomacy and trade. The Lenapes preserved their political sovereignty for the next fifty years as Dutch, Swedish, Finnish, and English colonists settled the Delaware Valley. The European outposts did not approach the size and strength of those in Virginia, New England, and New Netherland. Even after thousands of Quakers arrived in West New Jersey and Pennsylvania in the late 1670s and '80s, the region successfully avoided war for another seventy-five years. Lenape Country is a sweeping narrative history of the multiethnic society of the Delaware Valley in the seventeenth and early eighteenth centuries. After Swanendael, the Natives, Swedes, and Finns avoided war by focusing on trade and forging strategic alliances in such events as the Dutch conquest, the Mercurius affair, the Long Swede conspiracy, and English attempts to seize land. Drawing on a wide range of sources, author Jean R. Soderlund demonstrates that the hallmarks of Delaware Valley society—commitment to personal freedom, religious liberty, peaceful resolution of conflict, and opposition to hierarchical government—began in the Delaware Valley not with Quaker ideals or the leadership of William Penn but with the Lenape Indians, whose culture played a key role in shaping Delaware Valley society. The first comprehensive account of the Lenape Indians and their encounters with European settlers before Pennsylvania's founding, Lenape Country places Native culture at the center of this part of North America.
