This book provides a compact yet comprehensive overview of recentdevelopments in collisional-radiative (CR) modeling of laboratory andastrophysical plasmas.
This book describes a simple yet innovative method for performing Raman spectroscopy of samples submerged under liquid nitrogen. While Raman spectroscopy has proven to be a powerful tool for the characterization of the structure of matter in the gaseous, liquid, and solid phases, one major difficulty in its application has been laser damage to the material under investigation, especially for biological samples. This book demonstrates how immersion of the sample in liquid nitrogen protects the sample from thermal degradation and oxidation at high incident laser power and allows improvements in sensitivity and spectral resolution over room-temperature Raman spectroscopy, leading to the so-called RUN (Raman Spectroscopy Under liquid Nitrogen) technique. Cooling to liquid nitrogen temperature also allows the selection of the lowest energy molecular conformation for molecules which may have many low energy conformers. In addition, the presence of liquid nitrogen over a roughened surface improves the sensitivity of Surface Enhanced Raman Spectroscopy (SERS), enabling the closely related SERSUN (Surface-Enhanced Raman Spectroscopy Under liquid Nitrogen) technique. This book starts with the theoretical and experimental basics of Raman and polarized Raman spectroscopy, before moving on to detailed descriptions of RUN and SERSUN. Room temperature and RUN spectra are provided for over fifty molecules.
This book presents a self-contained derivation of van der Waals and Casimir type dispersion forces, covering the interactions between two atoms but also between microscopic, mesoscopic, and macroscopic objects of various shapes and materials.
The authors discuss particular implementations of the GMT methods, such as the Discrete Sources Method (DSM), Multiple Multipole Program (MMP), the Method of Auxiliary Sources (MAS), the Filamentary Current Method (FCM), the Method of Fictitious Sources (MFS) and the Null-Field Method with Discrete Sources (NFM-DS).
This book gives guidance to solve problems in electromagnetics, providing both examples of solving serious research problems as well as the original results to encourage further investigations.

Plasma Atomic Physics provides an overview of the elementary processes within atoms and ions in plasmas, and introduces readers to the language of atomic spectra and light emission, allowing them to explore the various and fascinating radiative properties of matter. The book familiarizes readers with the complex quantum-mechanical descriptions of electromagnetic and collisional processes, while also developing a number of effective qualitative models that will allow them to obtain adequately comprehensive descriptions of collisional-radiative processes in dense plasmas, dielectronic satellite emissions and autoionizing states, hollow ion X-ray emissions, polarized atoms and ions, hot electrons, charge exchange, atomic population kinetics, and radiation transport. Numerous applications to plasma spectroscopy and experimental data are presented, which concern magnetic confinement fusion, inertial fusion, laser-produced plasmas, and X-ray free-electron lasers' interaction with matter. Particular highlights include the development of quantum kinetics to a level surpassing the almost exclusively used quasi-classical approach in atomic population kinetics, the introduction of the recently developed Quantum-F-Matrix-Theory (QFMT) to study the impact of plasma microfields on atomic populations, and the Enrico Fermi equivalent photon method to develop the "Plasma Atom", where the response properties and oscillator strength distribution are represented with the help of a local plasma frequency of the atomic electron density.Based on courses held by the authors, this material will assist students and scientists studying the complex processes within atoms and ions in different kinds of plasmas by developing relatively simple but highly effective models. Considerable attention is paid to a number of qualitative models that deliver physical transparency, while extensive tables and formulas promote the practical and useful application of complex theories and provide effective tools for non-specialist readers.
This book discusses the physics of conductive channel development in space, air and vacuums and summarizes the attempts to create super-long conductive channels to study the upper atmosphere and to complete specific tasks related to energy transmission from the space to earth with high-voltage high repetition rate electrical sources.
This book provides an overview of the recent experimental and theoretical results on interactions of heavy ions with gaseous, solid and plasma targets from the perspective of atomic physics.
This book is devoted to theoretical methods used in the extreme circumstances of very strong electromagnetic fields. The development of high power lasers, ultrafast processes, manipulation of electromagnetic fields and the use of very fast charged particles interacting with other charges requires an adequate theoretical description.
The complex physical processes in high-frequency plasmas and arc plasmas, the internal and external parameters of plasma torches, near-electrode processes, heat transfer, the flow of solid particles in plasmas and other phenomena are considered.
Newly added and updatedtopics in this second edition include zonal flows, various versions of H modes,and steady-state operations of tokamak, the designconcept of ITER, therelaxation process of RFP, quasi-symmetric stellator, and tandem mirror.
Part II describes three methods for QED calculations, a) the standard S-matrix formulation, b) the Two-times Green's-function method, developed by the St Petersburg Atomic Theory group, and c) the Covariant-evolution operator (CEO) method, recently developed by the Gothenburg Atomic Theory group.
This book is about the drift, diffusion, and reaction of ions moving through gases under the influence of an external electric field, the gas temperature, and the number density.
This book focuses on the strong link existing between photon and electron interferences, highlighting the similarities and the differences.
For this purpose we have used the mathematical formalism, introduced in the Dirac theory of the electron by David Hestenes, based on the use of the real Cli?ord algebra Cl(M) associated with the Minkwoski space-time M, that is, the euclidean 4 R space of signature (1,3).
This book examines non-equilibrium "cold" plasmas via a chemical physics approach, using state-to-state plasma kinetics, which views each internal state as a new species with its own cross-sections. Includes examples in microelectronics, fusion, and aerospace.
This book examines the equations at the basis of the calculation of transport properties (thermal conductivity, diffusion coefficients, viscosity and electrical conductivity) of one-temperature and multi-temperature plasmas by using the Chapman-Enskog method.
This book presents a thorough treatment of plasma physics, beginning at an introductory level and proceeding to an extensive discussion of its applications in thermonuclear fusion research.
This book gives guidance to solve problems in electromagnetics, providing both examples of solving serious research problems as well as the original results to encourage further investigations.
