Book excerpt: From a stunning new voice in hard science fiction comes the thrilling story of one woman’s quest to wrest truth from chaos, love from violence, and reality from illusion in a post-human universe of emergent AIs, genetic constructs, and illegal wetware. . . . UN Peacekeeper Major Catherine Li has made thirty-seven faster-than-light jumps in her lifetime—and has probably forgotten more than most people remember. But that’s what backup hard drives are for. And Li should know; she’s been hacking her memory for fifteen years in order to pass as human. But no memory upgrade can prepare Li for what she finds on Compson’s World: a mining colony she once called home and to which she is sent after a botched raid puts her on the bad side of the powers that be. A dead physicist who just happens to be her cloned twin. A missing dataset that could change the interstellar balance of power and turn a cold war hot. And a mining “accident” that is starting to look more and more like murder. . . . Suddenly Li is chasing a killer in an alien world miles underground where everyone has a secret. And one wrong turn in streamspace, one misstep in the dark alleys of blackmarket tech and interstellar espionage, one risky hookup with an AI could literally blow her mind.

Available in PDF, EPUB and Kindle. Book excerpt: It has long been recognized that metal spin states play a central role in the reactivity of important biomolecules, in industrial catalysis and in spin crossover compounds. As the fields of inorganic chemistry and catalysis move towards the use of cheap, non-toxic first row transition metals, it is essential to understand the important role of spin states in influencing molecular structure, bonding and reactivity. Spin States in Biochemistry and Inorganic Chemistry provides a complete picture on the importance of spin states for reactivity in biochemistry and inorganic chemistry, presenting both theoretical and experimental perspectives. The successes and pitfalls of theoretical methods such as DFT, ligand-field theory and coupled cluster theory are discussed, and these methods are applied in studies throughout the book. Important spectroscopic techniques to determine spin states in transition metal complexes and proteins are explained, and the use of NMR for the analysis of spin densities is described. Topics covered include: DFT and ab initio wavefunction approaches to spin states Experimental techniques for determining spin states Molecular discovery in spin crossover Multiple spin state scenarios in organometallic reactivity and gas phase reactions Transition-metal complexes involving redox non-innocent ligands Polynuclear iron sulfur clusters Molecular magnetism NMR analysis of spin densities This book is a valuable reference for researchers working in bioinorganic and inorganic chemistry, computational chemistry, organometallic chemistry, catalysis, spin-crossover materials, materials science, biophysics and pharmaceutical chemistry.

Book excerpt: In this stunning follow-up to the critically acclaimed novel Spin State, Chris Moriarty depicts a grim future in which the final frontier may well be extinction. For as far-flung planets are terraformed and Earth’s age-old conflicts are contracted out to AIs, humanity is losing the only war that counts: the war for survival. Call Arkady a clone with a conscience. Or call him a traitor. A member of the space-faring Syndicates, Arkady has defected to Israel with a hot commodity: a genetic weapon powerful enough to wipe out humanity. But Israel’s not buying it. They’re selling it—and Arkady—to the highest bidder. As the auction heats up, the Artificial Life Emancipation Front sends in Major Catherine Li. Already drummed out of the Peacekeepers for “war crimes,” Li has now literally hooked up with an AI who has lived many lifetimes and shunted through many bodies. And while they each have their own definition of victory, together they have only one chance at survival. . . .

Download or read book CPT Invariance and the Spin Statistics Connection written by Jonathan Bain and published by Oxford University Press. This book was released on 2016-04-08 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book seeks to answer the question "What explains CPT invariance and the spin-statistics connection?" These properties play foundational roles in relativistic quantum field theories (RQFTs), are supported by high-precision experiments, and figure into explanations of a wide range of phenomena, from antimatter, to the periodic table of the elements, to superconductors and superfluids. They can be derived in RQFTs by means of the famous CPT and Spin-Statistics theorems; but, the author argues, these theorems cannot be said to explain these properties, at least under standard philosophical accounts of scientific explanation. This is because there are multiple, in some cases incompatible, ways of deriving these theorems, and, secondly, because the theorems fail for the types of theories that underwrite the empirical evidence: non-relativistic quantum theories, and realistic interacting RQFTs. The goal of this book is to work towards an understanding of CPT invariance and the spin-statistics connection by first providing an analysis of the necessary and sufficient conditions for these properties, and second by advocating a particular account of explanation appropriate for this context.

Download or read book Spin Squeezing and Non linear Atom Interferometry with Bose Einstein Condensates written by Christian Groß and published by Springer Science & Business Media. This book was released on 2012-01-13 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interferometry, the most precise measurement technique known today, exploits the wave-like nature of the atoms or photons in the interferometer. As expected from the laws of quantum mechanics, the granular, particle-like features of the individually independent atoms or photons are responsible for the precision limit, the shot noise limit. However this “classical” bound is not fundamental and it is the aim of quantum metrology to overcome it by employing entanglement among the particles. This work reports on the realization of spin-squeezed states suitable for atom interferometry. Spin squeezing was generated on the basis of motional and spin degrees of freedom, whereby the latter allowed the implementation of a full interferometer with quantum-enhanced precision.

Download or read book Long lived Nuclear Spin Order written by Giuseppe Pileio and published by Royal Society of Chemistry. This book was released on 2020-04-15 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea that a long-lived form of spin order, namely singlet order, can be prepared from nuclear spin magnetisation first emerged in 2004. The unusual properties of singlet order–its long lifetime and the fact that it is NMR silent but interconvertible into other forms of NMR active order—make it a ‘smart tag’ that can be used to store information for a long time or through distant space points. It is not unexpected then, that since its first appearance, this idea has caught the attention of research groups interested in exploiting this form of order in different fields of research spanning from biology to materials science and from hyperpolarisation to quantum computing. This first book on the subject gives a thorough description of the various aspects that affect the development of the topic and details the interdisciplinary applications. The book starts with a section dedicated to the basic theories of long-lived spin order and then proceeds with a description of the state-of-the-art experimental techniques developed to manipulate singlet order. It then concludes by covering the generalization of the concept of singlet order by introducing and discussing other forms of long-lived spin order.

Download or read book Spin Physics in Semiconductors written by Mikhail I. Dyakonov and published by Springer. This book was released on 2010-11-17 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this collective book is to present a non-exhaustive survey of sp- related phenomena in semiconductors with a focus on recent research. In some sense it may be regarded as an updated version of theOpticalOrientation book, which was entirely devoted to spin physics in bulk semiconductors. During the 24 years that have elapsed, we have witnessed, on the one hand, an extraordinary development in the wonderful semiconductor physics in two dim- sions with the accompanying revolutionary applications. On the other hand, during the last maybe 15 years there was a strong revival in the interest in spin phen- ena, in particular in low-dimensional semiconductor structures. While in the 1970s and 1980s the entire world population of researchers in the ?eld never exceeded 20 persons, now it can be counted by the hundreds and the number of publications by the thousands. This explosive growth is stimulated, to a large extent, by the hopes that the electron and/or nuclear spins in a semiconductor will help to accomplish the dream of factorizing large numbers by quantum computing and eventually to develop a new spin-based electronics, or “spintronics”. Whether any of this will happen or not, still remains to be seen. Anyway, these ideas have resulted in a large body of interesting and exciting research, which is a good thing by itself. The ?eld of spin physics in semiconductors is extremely rich and interesting with many spectacular effects in optics and transport.

Download or read book Spin Wave Theory and its Applications to Neutron Scattering and THz Spectroscopy written by Randy S Fishman and published by Morgan & Claypool Publishers. This book was released on 2018-11-05 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two of the most powerful tools used to study magnetic materials are inelastic neutron scattering and THz spectroscopy. Because the measured spectra provide a dynamical fingerprint of a magnetic material, those tools enable scientists to unravel the structure of complex magnetic states and to determine the microcscopic interactions that produce them. This book discusses the experimental techniques of inleastic neutron scattering and THz spectroscopy and provides the theoretical tools required to analyze their measurements using spin-wave theory. For most materials, this analysis can resolve the microscopic magnetic interactions such as exchange, anisotropy, and Dzyaloshinskii-Moriya interactions. Assuming a background in elementary statistical mechanics and a familiarity with the quantized harmonic oscillator, this book presents a comprehensive review of spin-wave theory and its applications to both inelastic neutron scattering and THz spectroscopy. Spin-wave theory is used to study several model magnetic systems, including non-collinear magnets such as spirals and cycloids that are produced by geometric frustration, competing exchange interactions, or Dzyaloshinskii-Moriya interactions. Several case studies utilizing spin-wave theory to analyze inelastic neutron-scattering and THz spectroscopy measurements are presented. These include both single crystals and powders and both oxides and molecule-based magnets. In addition to sketching the numerical techniques used to fit dynamical spectra based on microscopic models, this book also contains over 70 exercises that can be performed by beginning graduate students.

Available in PDF, EPUB and Kindle. Book excerpt: Frank Arntzenius presents a series of radical ideas about the structure of space and time, and establishes a new metaphysical position which holds that the fundamental structure of the physical world is purely geometrical structure. He argues that we should broaden our conceptual horizons and accept that spaces other than spacetime may exist.

Download or read book Spin Dynamics in Radical Pairs written by Alan Lewis and published by Springer. This book was released on 2018-09-12 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book sheds new light on the dynamical behaviour of electron spins in molecules containing two unpaired electrons (i.e. a radical pair). The quantum dynamics of these spins are made complicated by the interaction between the electrons and the many nuclear spins of the molecule; they are intractable using analytical techniques, and a naïve numerical diagonalization is not remotely possible using current computational resources. Hence, this book presents a new method for obtaining the exact quantum-mechanical dynamics of radical pairs with a modest number of nuclear spins. Readers will learn how a calculation that would take 13 years using conventional wavepacket propagation can now be done in 1 day, and will also discover a new semiclassical method for approximating the dynamics in the presence of many nuclear spins. The new methods covered in this book are shown to provide significant insights into three topical and diverse areas: charge recombination in molecular wires (which can be used in artificially mimicking photosynthesis), magnetoelectroluminescence in organic light-emitting diodes, and avian magnetoreception (how birds sense the Earth’s magnetic field in order to navigate).

Download or read book The Wonder of Quantum Spin written by Indubala I. Satija and published by Oxford University Press. This book was released on 2024-07-09 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Wonder of Quantum Spin is a confection of the history and the science of quantum spin sprinkled with quotations and excerpts from pioneers who lived and breathed science. The book unfolds two centuries of the golden era in mathematics and physics, where first glimpses of spin appeared nearly 200 years ago in the mathematics of rotations. In these studies, spinors emerged as a new entity that changes sign after a 360 degree rotation, reminiscent of the Mobius geometry. A century later, quantum spins described by spinors was discovered in physics in atomic spectra. This led to the discovery of antimatter and raised the possibility of parity violation. It gave the first warning that protons and neutrons are not elementary. As we approach the centennial of the discovery, the spin mystique prevails as we have no clue of what exactly is spinning. Nevertheless, the theoretical framework underlying the spin determines why we exist, and explains the mysteries of the 3000-year-old phenomenon of magnetism. This book showcases MRI - one of the most important medical advances of the 20th century with a tantalizing history of the application of nuclear spin to humanity. It narrates fascinating spin tales of the precision measurements of electron and muon spin magnetic moments displaying a mindboggling confrontation between theory and experiment that remains our ambassador to quantum physics.
