Spin-Wave Theory and its Applications to Neutron Scattering and THz Spectroscopy

By: Randy S Fishman,Jaime A Fernandez-Baca,Toomas Rõõm

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.

The Social Impulse

The Evolution and Neuroscience of What Brings Us Together

By: Jaime A. Pineda, Ph.D.

This book is an exploration of the integration-differentiation dynamics that result in a drive, or impulse, toward human sociality, arguing that our need to connect with other people is as fundamental as our need for food and shelter. In The Social Impulse: The Evolution and Neuroscience of What Brings Us Together, Jaime Pineda presents the evidence that social cohesion is a complementary force to natural selection, the Darwinian drive for differentiation and diversity. The book addresses the distinctive aspects of social behavior that arise from integration principles and seeks to answer the following questions: (1) Why does social cohesion arise? (2) What is the history of social dynamics? (3) How does social cohesion work? (4) When do the developmental aspects of social dynamics arise? A final section of the book addresses the value of sociality and social cohesion. By exploring the differences, similarities, and, most important, the interactivity between natural selection and social cohesion, this unique book provides a wealth of interesting, challenging, and unexpected insights.
