Figures Of Entanglement

Recent and ongoing "new materialisms" scholarship seeks to fundamentally reshape the humanities and their relationship with the sciences. While this work comprises multiple and varied currents, one of the most important, yet whose distinctive merits are arguably often underappreciated, is that influenced by the theoretical physicist and feminist philosopher Karen Barad. The first volume devoted to bringing Barad’s work into conversation with the disciplines of rhetoric and communication studies, this collection organizes that conversation primarily around her notion of "entanglement", which encourages an understanding of meaning as inherently performative, material, and ecological. In doing so, the essays in this collection variously approach rhetoric as a "figure of entanglement" in ways that contribute to and enrich both rhetoric and Barad’s theorizing. Topics range from politics to breast cancer, genealogy, the trope of academic "turns," Marx’s notion of exchange, and the "prehistoric" emergence of human consciousness. With a new foreword by the editors and afterword by Laurie E. Gries, this collection is otherwise reprinted from the 2016 "Figures of Entanglement" special issue of the journal Review of Communication.

The essays in this book broaden and enrich the scope, at once, of both rhetoric and Barad's theorizing through entangled reworkings of topics ranging from politics to breast cancer, genealogy, the trope of academic turns, Marx's notion of exchange, and the emergence of human consciousness.

This monograph forms an interdisciplinary study in atomic, molecular, and quantum information (QI) science. Here a reader will find that applications of the tools developed in QI provide new physical insights into electron optics as well as properties of atoms & molecules which, in turn, are useful in studying QI both at fundamental and applied levels. In particular, this book investigates entanglement properties of flying electronic qubits generated in some of the well known processes capable of taking place in an atom or a molecule following the absorption of a photon. Here, one can generate Coulombic or fine-structure entanglement of electronic qubits. The properties of these entanglements differ not only from each other, but also from those when spin of an inner-shell photoelectron is entangled with the polarization of the subsequent fluorescence. Spins of an outer-shell electron and of a residual photoion can have free or bound entanglement in a laboratory.

This book provides a comprehensive overview of developments in the field of holographic entanglement entropy. Within the context of the AdS/CFT correspondence, it is shown how quantum entanglement is computed by the area of certain extremal surfaces. The general lessons one can learn from this connection are drawn out for quantum field theories, many-body physics, and quantum gravity. An overview of the necessary background material is provided together with a flavor of the exciting open questions that are currently being discussed. The book is divided into four main parts. In the first part, the concept of entanglement, and methods for computing it, in quantum field theories is reviewed. In the second part, an overview of the AdS/CFT correspondence is given and the holographic entanglement entropy prescription is explained. In the third part, the time-dependence of entanglement entropy in out-of-equilibrium systems, and applications to many body physics are explored using holographic methods. The last part focuses on the connection between entanglement and geometry. Known constraints on the holographic map, as well as, elaboration of entanglement being a fundamental building block of geometry are explained. The book is a useful resource for researchers and graduate students interested in string theory and holography, condensed matter and quantum information, as it tries to connect these different subjects linked by the common theme of quantum entanglement.

A theoretical physicist and feminist theorist, Karen Barad elaborates her theory of agential realism, a schema that is at once a new epistemology, ontology, and ethics.

Entanglement theory posits that the interrelationship of humans and objects is a delimiting characteristic of human history and culture. This edited volume of original studies by leading archaeological theorists applies this concept to a broad range of topics, including archaeological science, heritage, and theory itself. In the theoretical explications and ten case studies, the editors and contributing authors: • build on the intersections between science, humanities and ecology to provide a more fine-grained, multi-scalar treatment emanating from the long-term perspective that characterizes archaeological research; • bring to light the subtle and unacknowledged paths that configure historical circumstances and bind human intentionality; • examine the constructions of personhood, the rigidity of path dependencies, the unpredictable connections between humans and objects and the intricate paths of past events in varied geographic and historical contexts that channel future actions. This broad focus is inclusive of early complex developments in Asia and Europe, imperial and state strategies in the Andes and Mesoamerica, continuities of postcolonialism in North America, and the unforeseen and complex consequences that derive from archaeological practices. This volume will appeal to archaeologists and their advanced students.

By foregrounding the ways that human existence is bound together with the lives of other entities, contemporary cultural theorists have sought to move beyond an anthropocentric worldview. Yet as Eva Haifa Giraud contends in What Comes after Entanglement?, for all their conceptual power in implicating humans in ecologically damaging practices, these theories can undermine scope for political action. Drawing inspiration from activist projects between the 1980s and the present that range from anticapitalist media experiments and vegan food activism to social media campaigns against animal research, Giraud explores possibilities for action while fleshing out the tensions between theory and practice. Rather than an activist ethics based solely on relationality and entanglement, Giraud calls for what she describes as an ethics of exclusion, which would attend to the entities, practices, and ways of being that are foreclosed when other entangled realities are realized. Such an ethics of exclusion emphasizes foreclosures in the context of human entanglement in order to foster the conditions for people to create meaningful political change.

Historically speaking, theology can be said to operate “materiaphobically.” Protestant Christianity in particular has bestowed upon theology a privilege of the soul over the body and belief over practice, in line with the distinction between a disembodied God and the inanimate world “He” created. Like all other human, social, and natural sciences, religious studies imported these theological dualisms into a purportedly secular modernity, mapping them furthermore onto the distinction between a rational, “enlightened” Europe on the one hand and a variously emotional, “primitive,” and “animist” non-Europe on the other. The “new materialisms” currently coursing through cultural, feminist, political, and queer theories seek to displace human privilege by attending to the agency of matter itself. Far from being passive or inert, they show us that matter acts, creates, destroys, and transforms—and, as such, is more of a process than a thing. Entangled Worlds examines the intersections of religion and new and old materialisms. Calling upon an interdisciplinary throng of scholars in science studies, religious studies, and theology, it assembles a multiplicity of experimental perspectives on materiality: What is matter, how does it materialize, and what sorts of worlds are enacted in its varied entanglements with divinity? While both theology and religious studies have over the past few decades come to prioritize the material contexts and bodily ecologies of more-than-human life, Entangled Worlds sets forth the first multivocal conversation between religious studies, theology, and the body of “the new materialism.” Here disciplines and traditions touch, transgress, and contaminate one another across their several carefully specified contexts. And in the responsiveness of this mutual touching of science, religion, philosophy, and theology, the growing complexity of our entanglements takes on a consistent ethical texture of urgency.
