Book Description
This thesis investigates the structure and behaviour of entanglement, the purely quantum mechanical part of correlations, in many-body systems, employing both numerical and analytical techniques at the interface of condensed matter theory and quantum information theory. Entanglement can be seen as a precious resource which, for example, enables the noiseless and instant transmission of quantum information, provided the communicating parties share a sufficient "amount" of it. Furthermore, measures of entanglement of a quantum mechanical state are perceived as useful probes of collective properties of many-body systems. For instance, certain measures are capable of detecting and classifying ground-state phases and, particularly, transition (or critical) points separating such phases. Chapters 2 and 3 focus on entanglement in many-body systems and its use as a potential resource for communication protocols. They address the questions of how a substantial amount of entanglement can be established between distant subsystems, and how efficiently this entanglement could be "harvested" by way of measurements. The subsequent chapters 4 and 5 are devoted to universality of entanglement between large collections of particles undergoing a quantum phase transition, where, despite the enormous complexity of these systems, collective properties including entanglement no longer depend crucially on the microscopic details.

Book Description
This book presents a selection of advanced lectures from leading researchers, providing recent theoretical results on strongly coupled quantum field theories. It also analyzes their use for describing new quantum states, which are physically realizable in condensed matter, cold-atomic systems, as well as artificial materials. It particularly focuses on the engineering of these states in quantum devices and novel materials useful for quantum information processing. The book offers graduate students and young researchers in the field of modern condensed matter theory an updated review of the most relevant theoretical methods used in strongly coupled field theory and string theory. It also provides the tools for understanding their relevance in describing the emergence of new quantum states in a variety of physical settings. Specifically, this proceedings book summarizes new and previously unrelated developments in modern condensed matter physics, in particular: the interface of condensed matter theory and quantum information theory; the interface of condensed matter physics and the mathematics emerging from the classification of the topological phases of matter, such as topological insulators and topological superconductors; and the simulation of condensed matter systems with cold atoms in optical lattices.

Book Description
This book covers recent developments in the understanding, quantification, and exploitation of entanglement in spin chain models from both condensed matter and quantum information perspectives. Spin chain models are at the foundation of condensed matter physics and quantum information technologies and elucidate many fundamental phenomena such as information scrambling, quantum phase transitions, and many-body localization. Moreover, many quantum materials and emerging quantum devices are well described by spin chains. Comprising accessible, self-contained chapters written by leading researchers, this book is essential reading for graduate students and researchers in quantum materials and quantum information. The coverage is comprehensive, from the fundamental entanglement aspects of quantum criticality, non-equilibrium dynamics, classical and quantum simulation of spin chains through to their experimental realizations, and beyond into machine learning applications.

Book Description
The structural aspects of composite quantum systems in the foundation, interpretation and application of quantum theory is an increasingly prominent topic of physics research. As an emerging field, it seeks to understand the origins of the classical world of experience from the quantum level.Quantum Structural Studies presents conceptual fundamentals and mathematical methods for investigating the structuring of quantum systems into subsystems. Split into four sections, the topics covered include the historical and philosophical aspects of quantum structures, specific interpretive approaches and ontologies, and alternative methodological approaches to quantum mechanics. Questions addressed are: Specialists, graduate students and researchers seeking an introduction to the field of emergent structures and new directions for research and experimentation can use this book to find up-to-date representative texts and reviews.

Book Description
The Things of Others: Ethnographies, Histories, and Other Artefacts deals with the things mainly, but not only, mobilized by anthropologists in order to produce knowledge about the African American, the Afro-Brazilian and the Afro-Cuban during the 1930s. However, the book's goal is not to dig up evidence of the creation of an epistemology of knowledge and its transnational connections. The research on which this book is based suggests that the artefacts created in fieldwork, offices, libraries, laboratories, museums, and other places and experiences – beyond the important fact that these places and situations involved actors other than the anthropologists themselves – have been different things during their troubled existence. The book seeks to make these differences apparent, highlighting rather than concealing the relationships between partial modes of making and being ‘Afro’ as a subject of science. If the artefacts created in a variety of situations have been different things, we should ask what sort of things they were and how the actors involved in their creation sought to make them meaningful. The book foregrounds these discontinuous and ever-changing contours.

Book Description
Examining international case studies including USA, Asia, Australia and New Zealand, this book identifies and explores the use of heritage throughout the world. Challenging the idea that heritage value is self-evident, and that things must be preserved, it demonstrates how it gives tangibility to the values that underpin different communities.

Book Description
In Biomedical Hegemony and Democracy in South Africa Ngambouk Vitalis Pemunta and Tabi Chama-James Tabenyang unpack the contentious South African government’s post-apartheid policy framework of the ‘‘return to tradition policy’’. The conjuncture between deep sociopolitical crises, witchcraft, the ravaging HIV/AIDS pandemic and the government’s initial reluctance to adopt antiretroviral therapy turned away desperate HIV/AIDS patients to traditional healers. Drawing on historical sources, policy documents and ethnographic interviews, Pemunta and Tabenyang convincingly demonstrate that despite biomedical hegemony, patients and members of their therapy-seeking group often shuttle between modern and traditional medicine, thereby making both systems of healthcare complementary rather than alternatives. They draw the attention of policy-makers to the need to be aware of ‘‘subaltern health narratives’’ in designing health policy.

Book Description
New York Times bestseller • Life on the Edge alters our understanding of our world's fundamental dynamics through the use of quantum mechanics. Life is the most extraordinary phenomenon in the known universe; but how did it come to be? Even in an age of cloning and artificial biology, the remarkable truth remains: nobody has ever made anything living entirely out of dead material. Life remains the only way to make life. Are we still missing a vital ingredient in its creation? Using first-hand experience at the cutting edge of science, Jim Al-Khalili and Johnjoe Macfadden reveal that missing ingredient to be quantum mechanics. Drawing on recent ground-breaking experiments around the world, each chapter in Life on the Edge illustrates one of life's puzzles: How do migrating birds know where to go? How do we really smell the scent of a rose? How do our genes copy themselves with such precision? Life on the Edge accessibly reveals how quantum mechanics can answer these probing questions of the universe. Guiding the reader through the rapidly unfolding discoveries of the last few years, Al-Khalili and McFadden describe the explosive new field of quantum biology and its potentially revolutionary applications, while offering insights into the biggest puzzle of all: what is life? As they brilliantly demonstrate in these groundbreaking pages, life exists on the quantum edge. Winner, Stephen Hawking Medal for Science Communication
