Thermal Fluctuations and Relaxation Processes in Nanomagnets

William T Coffey

Presenting in a coherent and accessible fashion current results in nanomagnetism, this book constitutes a comprehensive, rigorous and readable account, from first principles of the classical and quantum theories underlying the dynamics of magnetic nanoparticles subject to thermal fluctuations.
Starting with the Larmor-like equation for a giant spin, both the stochastic (Langevin) equation of motion of the magnetization and the associated evolution (Fokker–Planck) equation for the distribution function of the magnetization orientations of ferromagnetic nanoparticles (classical spins) in a heat bath are developed along with their solution (using angular momentum theory) for arbitrary magnetocrystalline-Zeeman energy. Thus, observables such as the magnetization reversal time, relaxation functions, dynamic susceptibilities, etc. are calculated and compared with the predictions of classical escape rate theory including in the most general case spin-torque-transfer. Regarding quantum effects, which are based on the reduced spin density matrix evolution equation in Hilbert space as is described at length, they are comprehensively treated via the Wigner–Stratonovich formulation of the quantum mechanics of spins via their orientational quasi-probability distributions on a classically meaningful representation space. Here, as suggested by the relevant Weyl symbols, the latter is the configuration space of the polar angles. Hence, one is led, by mapping the reduced density matrix equation onto that space, to a master equation for the quasi-probability evolution akin to the Fokker–Planck equation which may be solved in a similar way. Thus, one may study in a classical-like manner the evolution of observables with spin number ranging from an elementary spin to molecular clusters to the classical limit, viz. a nanoparticle. The entire discussion hinges on the one-to-one correspondence between polarization operators in Hilbert space and the spherical harmonics allied to concepts of spin coherent states long familiar in quantum optics.
Catering for the reader with only a passing knowledge of statistical and quantum mechanics, the book serves as an introductory text on a complicated subject where the literature is remarkably sparse.

Ultracold Neutrons

Albert Steyerl

Ultracold Neutrons is a guide to a fascinating topic. It describes how a simple new idea in experimental neutron physics has changed the landscape of what is often called 'fundamental physics.' Ultracold neutrons (UCNs) are neutrons moving at the low speed of a bicycle rider. They were produced for the first time 50 years ago (in 1968) and are distinguished from ordinary neutrons with much higher energies by their ability to be confined in 'neutron bottles' for durations up to several hundred seconds. This is possible since they are reflected back and forth from the container walls many thousands of times with very little loss. As a result of these long observation times, their properties and interactions with the environment can be studied with superb precision.Directed towards a general readership, this book is an excellent introduction to a field of research that is not highly specialized but touches on many aspects of our physical world, classical as well as quantum mechanical.Contents: <ul><li>Introduction</li><li>The Early History of Very Low Energy Neutrons</li><li>Neutron Interactions Relevant in the UCN Energy Range</li><li>Sources of Ultracold Neutrons</li><li>Total Cross-Section Measurements with Very Low Energy Neutrons</li><li>UCN and VCN Reflection, Transmission and Scattering at Material Walls</li><li>Neutron Optical Experiments Probing the Wave Properties of Ultracold Neutrons</li><li>High-Resolution UCN Spectroscopy</li><li>Possibility of Microscopy and Interferometry with Ultracold Neutrons</li><li>Gravitational Quantum States of the Neutron</li><li>Measurement of the Neutron Lifetime for Beta Decay</li><li>Search for the Electric Dipole Moment of the Neutron Using Stored Ultracold Neutrons</li><li>Further UCN Applications in Fundamental Physics</li><li>Appendices</li></ul> Readership: General audience with interest in fundamental physics.

Tennis Science for Tennis Players

Howard Brody

How does your opponent put that tricky spin on the ball? Why are some serves easier to return than others? The mysteries behind the winning strokes, equipment, and surfaces of the game of tennis are accessibly explained by Howard Brody through the laws of physics. And he gives practical pointers to ways players can use this understanding to advantage in the game. Through extensive laboratory testing and computer modeling, Brody has investigated the physics behind the shape of the tennis racket, the string pattern, the bounce of the tennis ball, the ways a particular court surface can determine the speed of the game, and the many other physical factors involved in tennis.

Pear-Shaped Nuclei

Suresh C Pancholi

During the last several decades, the study of nuclear shapes has been of prime importance. A large number of investigations, both theoretical and experimental, have led to the discovery of a rich variety of nuclear shapes like, the basic spherical, deformed, superdeformed, triaxial, shape coexistence, reflection asymmetric (pear-shape) and other exotic ones. Apart from common nuclear structural properties, each of the mentioned shapes manifests properties associated with its specific form. It is interesting to note that most deformed nuclei are prolate deformed. In this monograph, attention is paid to pear-shaped nuclei.Contents: <ul><li>The Pear-Shaped Nuclei</li><li>Ground-State Nuclear Shape Deformations</li><li>High Spin Behavior of Pear-Shaped Nuclei — I</li><li>High Spin Behavior of Pear-Shaped Nuclei — II</li><li>Status, Conclusions and Perspectives</li></ul> Readership: Advance nuclear physics students and young researchers in nuclear structure physics.Nuclear Structure Physics;Pear-shaped Nuclei0Key Features:<ul><li>A pedagogical approach for beginners in research or young researchers in nuclear structure physics</li><li>Provides the readers with an up-to-date subject knowledge in a consolidated and focused manner</li><li>Will be very useful for advanced nuclear physics class teaching in Universities and Institutions</li><li>Based on numerous painstaking investigations, both theoretical and experimental, over several decades by a large number of physicists</li> <li>Emphasis more on experimental findings</li></ul>

Machining for Hobbyists

Karl Moltrecht

Machining for Hobbyists is for do-it-yourselfers and hobbyists who want to set up or expand a small machine shop in their garage, basement, shed or perhaps in a rented space. With their own shop, hobbyists can build models and undertake other building and maintenance projects that involve using different metals. Working in metal requires skills, knowledge, and equipment that are unlike other hobbies.Through easy-to-follow explanations, as well as detailed illustrations and color photography, Machining for HobbyistsGuides hobbyists in selecting the proper tools for working with metal, including tips for buying and using bench-top lathes, mills and drill presses. The book also covers the various cutting components used on these tools. Provides suggestions for shop layout, including space requirements, lighting, ventilation, and safety.Guides the reader through the use of specialty tools used for measuring and handling small metal parts.

Mean Field Theory

Vladimir M Kolomietz

This book describes recent theoretical and experimental developments in the study of static and dynamic properties of atomic nuclei, many-body systems of strongly interacting neutrons and protons. The theoretical approach is based on the concept of the mean field, describing the motion of a nucleon in terms of a self-consistent single-particle potential well which approximates the interactions of a nucleon with all the other nucleons. The theoretical approaches also go beyond the mean-field approximation by including the effects of two-body collisions. The self-consistent mean-field approximation is derived using the effective nucleon–nucleon Skyrme-type interaction. The many-body problem is described next in terms of the Wigner phase space of the one-body density, which provides a basis for semi-classical approximations and leads to kinetic equations. Results of static properties of nuclei and properties associated with small amplitude dynamics are also presented. Relaxation processes, due to nucleon–nucleon collisions, are discussed next, followed by instability and large amplitude motion of excited nuclei. Lastly, the book ends with the dynamics of hot nuclei. The concepts and methods developed in this book can be used for describing properties of other many-body systems.
