Book Description
This thesis presents the first ever measurement of the noise emitted by magnetic monopoles and the development of an exquisitely sensitive magnetic-field-noise spectrometer based on a superconducting quantum interference device (SQUID) that enabled it. Magnetic monopoles are highly elusive elementary particles exhibiting quantized magnetic charge. The prospects for studying them brightened recently with the theoretical discovery that the thermally excited states in certain classes of magnetic insulators exhibit all the characteristics of magnetic monopoles. Furthermore, in 2018, it was predicted that the random motion of magnetic monopoles inside would generate a very specific kind of magnetization noise. In this thesis, the author describes a new experimental technique, so-called spin noise spectroscopy, and the subsequent discovery of virtually all of the predicted features of the magnetic noise expected from a dense fluid of magnetic monopoles in crystals of Dy2Ti2O7. Remarkably, because this magnetic monopole noise occurs in the frequency range below 20kHz, when amplified by the SQUID it is actually audible to humans.

Book Description
These lecture notes discusses the developments both in the theoretical understanding of the physics and mathematics of magnetic monopoles as well as the ways in which they can be detected experimentally.The subject has now become highly interdisciplinary and recent monopole meetings have attracted participants from low temperature physics at one extreme to cosmology at the other.

Book Description
An award-winning Oxford physicist draws on classic sci-fi, fantasy fiction, and everyday phenomena to explain and celebrate the magical properties of the world around us. If you were to present the feats of modern science to someone from the past, those feats would surely be considered magic. Theoretical physicist Felix Flicker proves that they are indeed magic—just familiar magic. The name for this magic is “condensed matter physics.” Most people haven’t heard of the field, yet more than a third of physicists identify as condensed matter researchers, making it the most active area in the subject—with good reason. Condensed matter is the solids, liquids, and gasses that surround us—and the more exotic matters—which dictate every aspect of our present existence, and hold the keys to a brighter future, from quantum computing to real-life invisibility cloaks. Flicker teases out the magical threads that run through our daily lives. Condensed matter physics allows you to create anything abiding by the laws of reality—and often, we find that those laws can be bent. Flicker explains how to create new particles which never existed before, how to make crystals shoot out such intense light they can cut through metal, how to separate the poles of a magnet. And more. The book’s endearing conceit is that you, the reader, are an aspiring wizard whose ability to cast spells (i.e. to do science) is dependent on your grasp of the fundamentals of our universe. This book contains no equations or charts—instead, it’s full of owls and mountains and infinite libraries, and staffs and wands, and martial arts and mythical islands ruled by sage knot-makers. Part of the book’s magic is that, for all these fanciful trappings, it still feels practical and applicable. The Magick of Physics will open your eyes to the miracles that surround us.

Book Description
'Sensors' is the first self-contained series to deal with the whole area of sensors. It describes general aspects, technical and physical fundamentals, construction, function, applications and developments of the various types of sensors. This volume presents for the first time a comprehensive description of magnetic sensors with special emphasis placed upon technical and scientific fundamentals. It provides important definitions and a unique overview of concepts, and the nature and principles of magnetic fields. General questions concerning all types of magnetic sensors, such as those pertaining to material, noise, etc. are treated. Each chapter contains physical and mathematical fundamentals and applied technical concepts. In addition, each chapter presents an outline of the most important applications, measurement ranges and accuracy of sensing etc. This volume is an indispensable reference work and text book for both specialists and newcomers, researcher and developers.

Book Description
The noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is a critical feature for customers to assess the performance and quality of vehicles. NVH characteristics are higher among factors that customers use to judge the vehicle's quality.This book sets out to introduce the basic concepts, principles, and applications of the NVH development and refi nement of Battery Electric Vehicles (BEV), Hybrid Electric Vehicles (HEV), and Fuel Cell Electric Vehicles. Each type comes with its own set of challenges.

Book Description
Matter and Interactions offers a modern curriculum for introductory physics (calculus-based). It presents physics the way practicing physicists view their discipline and integrates 20th Century physics and computational physics. The text emphasizes the small number of fundamental principles that underlie the behavior of matter, and models that can explain and predict a wide variety of physical phenomena. Matter and Interactions will be available as a single volume hardcover text and also two paperback volumes.

Book Description
Functional Magnetic Resonance Imaging (fMRI) has become a standard tool for mapping the working brain's activation patterns, both in health and in disease. It is an interdisciplinary field and crosses the borders of neuroscience, psychology, psychiatry, radiology, mathematics, physics and engineering. Developments in techniques, procedures and our understanding of this field are expanding rapidly. In this second edition of Introduction to Functional Magnetic Resonance Imaging, Richard Buxton – a leading authority on fMRI – provides an invaluable guide to how fMRI works, from introducing the basic ideas and principles to the underlying physics and physiology. He covers the relationship between fMRI and other imaging techniques and includes a guide to the statistical analysis of fMRI data. This book will be useful both to the experienced radiographer, and the clinician or researcher with no previous knowledge of the technology.
