Atoms, Molecules and Photons

Atoms, Molecules and Photons

This introduction to Atomic and Molecular Physics explains how our present model of atoms and molecules has been developed over the last two centuries, both by many experimental discoveries and, from the theoretical side, by the introduction of quantum physics to the adequate description of micro-particles. It illustrates the wave model of particles by many examples and shows the limits of classical description. The interaction of electromagnetic radiation with atoms and molecules and its potential for spectroscopy is outlined in great detail and, in particular, lasers as modern spectroscopic tools are discussed thoroughly. Many examples and problems with solutions are offered to encourage readers to actively participate in applying and adapting the fundamental physics presented in this textbook to specific situations.

New Trends in Atomic and Molecular Physics

New Trends in Atomic and Molecular Physics

The field of Atomic and Molecular Physics (AMP) has reached significant advances in highprecision experimental measurement techniques. The area covers a wide spectrum ranging from conventional to new emerging multi-disciplinary areas like physics of highly charged ions (HCI), molecular physics, optical science, ultrafast laser technology etc. This book includes the important topics of atomic structure, physics of atomic collision, photoexcitation, photoionization processes, Laser cooling and trapping, Bose Einstein condensation and advanced technology applications of AMP in the fields of astronomy, astrophysics, fusion, biology and nanotechnology. This book is useful for researchers, professors, graduate, postgraduate and PhD students dealing with atomic and molecular physics. The book has a wide scope with applications in neighboring fields like plasma physics, astrophysics, cold collisions, nanotechnology and future fusion energy sources like ITER (international Thermonuclear Experimental Reactor) Tokomak plasma machine, which need accurate AMP data.

Atoms in Plasmas

Atoms in Plasmas

A study of radiative-collisional phenomena in neutral and ionized gases, focusing on a ‘perturbed atom’, i.e an atom under the influence of different perturbations in plasmas, namely by electrical and magnetic fields. The treatment covers fundamental aspects of modern physics, such as atomic quantum mechanics and quantum optics, radiation and collisional processes in plasmas and gases, nonlinear laser spectroscopy, and plasma diagnostics.

Quasicrystals

Quasicrystals

The book provides an introduction to all aspects of the physics of quasicrystals. The chapters, each written by an expert in this field, cover quasiperiodic tilings and the modeling of the atomic structure of quasicrystals. The electronic density of states and the calculation of the electronic structure play a key role in this introduction, as does an extensive discussion of the atomic dynamics. The study of defects in quasicrystals by high resolution electron microscopy and the computer simulations of defects and fracture in decorated tilings are important subjects for the application of these aperiodic crystals.

Analytical Atomic Spectrometry with Flames and Plasmas

Analytical Atomic Spectrometry with Flames and Plasmas

This completely revised second edition of the standard work has been expanded by some twenty percent to include more information on the latest developments and new apparatus. In particular, sections have been added on microplasmas and new types of spectrometers, while that on the rapidly expanding field of speciations with practical examples from life and environmental sciences have been included.

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.

Mossbauer Analysis of the Atomic and Magnetic Structure of Alloys

Mossbauer Analysis of the Atomic and Magnetic Structure of Alloys

The nuclear gamma resonance method or the Mossbauer effect, is one of the most powerful methods of examining the structure of matter and substances. The monograph indicates the key problems that have to be solved for the further development of the Mossbauer methods for analysis of the nuclear and magnetic structure of alloys, and offer solution variants for some of these problems based on the generalised results of a wide range of theoretical and experimental investigations, including original work by the author of the book and his

Bose-Einstein Condensation in Dilute Gases

Bose-Einstein Condensation in Dilute Gases

In 1925 Einstein predicted that at low temperatures particles in a gas could all reside in the same quantum state. This gaseous state, a BoseEinstein condensate, was produced in the laboratory for the first time in 1995 and investigating such condensates has become one of the most active areas in contemporary physics. The study of BoseEinstein condensates in dilute gases encompasses a number of different subfields of physics, including atomic, condensed matter, and nuclear physics. The authors of this graduate-level textbook explain this exciting new subject in terms of basic physical principles, without assuming detailed knowledge of any of these subfields. Chapters cover the statistical physics of trapped gases, atomic properties, cooling and trapping atoms, interatomic interactions, structure of trapped condensates, collective modes, rotating condensates, superfluidity, interference phenomena, and trapped Fermi gases. Problem sets are also included in each chapter.
