Axions

Axions

Axions are peculiar hypothetical particles that could both solve the CP problem of quantum chromodynamics and at the same time account for the dark matter of the universe. Based on a series of lectures by world experts in this field held at CERN (Geneva), this volume provides a pedagogical introduction to the theory, cosmology and astrophysics of these fascinating particles and gives an up-to-date account of the status and prospect of ongoing and planned experimental searches. Learners and practitioners of astroparticle physics will find in this book both a concise introduction and a current reference work to a showcase topic that connects the ‘inner space’ of the elementary particle world with the ‘outer space’ of the universe at large.

Energetic Materials

Energetic Materials

Incorporation of particular components with specialized properties allows one to tailor the end product’s properties. For instance, the sensitivity, burning behavior, thermal or mechanical properties or stability of energetic materials can be affected and even controllably varied through incorporation of such ingredients. This book examines particle technologies as applied to energetic materials such as propellants and explosives, thus filling a void in the literature on this subject.

Gravitation

Gravitation

Although gravity is the dominant force of nature at large distances (from intermediate scales to the Hubble length), it is the weakest of forces in particle physics, though it is believed to become important again at very short scales (the Planck length). The conditions created in particle accelerators are similar to those at the time of the early universe. While particle physics offers insight to early universe physics, there is a need to understand gravity at extremes of large and short distances to further understand cosmology and the development of the universe. Gravitation: From the Hubble Length to the Planck Length fulfills this need by providing an overview of relativistic astrophysics, early universe physics, cosmology, and their interface with particle physics.

Particles, Sources and Fields, Volume 3

Continuing Dr. Schwinger’s work in the field of electrodynamics, this last volume of the trilogy focuses on the two-particle problem and applications to hydrogenic atoms, positronium, and muonium. Attention also is given to the effect of strong magnetic fields, to an extended treatment of the photon propagation function, and to a confrontational discussion of the pion decay into two photons.

The Fundamental Constants

The Fundamental Constants

The speed of light, the fine structure constant, and Newton’s constant of gravity – these are just three among the many physical constants that define our picture of the world. Where do they come from? Are they constant in time and across space? In this book, physicist and author Harald Fritzsch invites the reader to explore the mystery of the fundamental constants of physics in the company of Isaac Newton, Albert Einstein, and a modern-day physicist. The conversation that the three scientists are imagined to have provides an entertaining introduction to the constants and covers topics ranging from atomic, nuclear, and particle physics to astrophysics and cosmology.

Numerical particle-in-cell Methods

Numerical particle-in-cell Methods

Algorithms known as ‘particle’ methods, whose characteristic feature is the discretization technique when the set of discrete objects is introduced, which are model ‘particles’ considered as some mesh of moving nodes, are becoming more and more widespread in mathematical modelling. Until recently, particle methods have mainly been developed as an alternative to classical numerical methods for solving problems in some applied domains of physics and mathematics. As a result, no specialized monographs on this subject have been available.
