The first comprehensive and authoritative coverage of the angular momentum of light, illustrating both its theoretical and applied aspects.
Anthropology of Law in Muslim Sudan analyses the hybridity of law systems and the plurality of legal practices in rural and urban contexts of contemporary Sudan, shedding light on the complex relation between Islam and society. It is the outcome of the international research program ANDROMAQUE (Anthropologie du Droit dans les Mondes Musulmans Africains et Asiatiques), funded by the French ANR (Agence National de la Recherche) between 2011 and 2014. Crossing two disciplinary perspectives, anthropology and law, the present volume contains original fieldwork data on contemporary urban and rural Sudan. Focusing on two major domains, land property and courts, several case studies demonstrate the ...
Advances in nanotechnology have generated semiconductor structures that are only a few molecular layers thick, and this has important consequences for the physics of electrons and phonons in such structures. This book describes in detail how confinement of electrons and phonons in quantum wells and wires affects the physical properties of the semiconductor. This second edition contains four new chapters on spin relaxation, based on recent theoretical research; the hexagonal wurtzite lattice; nitride structures, whose novel properties stem from their spontaneous electric polarization; and terahertz sources, which includes an account of the controversies that surrounded the concepts of Bloch oscillations and Wannier-Stark states. The book is unique in describing the microscopic theory of optical phonons, the radical change in their nature due to confinement, and how they interact with electrons. It will interest graduate students and researchers working in semiconductor physics.

Cottam and Tilley provide an introduction to the properties of wave-like excitations associated with surfaces and interfaces. The emphasis is on acoustic, optic and magnetic excitations, and apart from one section on liquid surfaces, the text concentrates on solids. The important topic of superlattices is also discussed, in which the different kinds of excitation are considered from a unified point of view. Throughout the book, the authors are careful to relate theory and experiment and all of the most important experimental techniques are described. The theoretical treatment assumes only a knowledge of undergraduate physics, except for Green function methods that are used in a few sections; these methods are developed in an appendix. The book also contains extensive references, enabling the reader to consult the research and review literature. Each of the main chapters contains problems to allow the reader to develop topics presented in the text.

Monitoring of Harmful Algae Blooms is a timely guide to the research techniques in use to monitor visible algae blooms and through remote sensing, including infrared techniques, predict them through mathematical modeling. Drawing on current and future satellite data, the book presents visible perspectives on a more efficient HAB monitoring system for the future. It also emphasizes practical applications, impacting on marine ecology, national economy, health, food and safety and quality assurance.
The prohibition of torture and other cruel, inhuman, degrading treatment or punishment has a special status. It is the foremost international human rights norm protecting persons from attacks on their dignity and integrity. Consequently, it has been at the forefront of a series of developments in international human rights law and international law more broadly. Having withstood sustained challenges to its absolute nature in the 'war on terror', it has broadened its scope of application, becoming more sophisticated and complex in the process. The prohibition of torture increasingly interacts with other fields of human rights law, such as non-discrimination law, international criminal law, in...
In 1861, James Clerk-Maxwell published Part II of his four-part series 'On physical lines of force'. In it, he attempted to construct a vortex model of the magnetic field but after much effort neither he, nor other late nineteenth century physicists who followed him, managed to produce a workable theory. What survived from these attempts were Maxwell's four equations of electrodynamics together with the Lorentz force law, formulae that made no attempt to describe an underlying reality but stood only as a mathematical description of the observed phenomena. When the quantum of action was introduced by Planck in 1900 the difficulties that had faced Maxwell's generation were still unresolved. Since then theories of increasing mathematical complexity have been constructed to attempt to bring the totality of phenomena into order with little success. This work examines the problems that had been abandoned long before quantum mechanics was formulated in 1925 and argues that these issues need to be revisited before real progress in the quantum theory of the electromagnetic field can be made.
