This book provides a throrough introduction to the interaction of atoms and atomic ions with optical and magnetic fields. The author places particular emphasis on the wealth of important multilevel effects, where atomic vapors exhibit anisotropic behavior. As well as covering the classic two-level atom approach to light-atom interactions, Suter describes in detail a general multilevel formalism, which he uses to discuss optical pumping, two-dimensional spectroscopy and nonlinear optical dynamics. The final chapter deals with the mechanical effects of light, including the cooling and trapping of atoms. With full theoretical and experimental coverage, and over 250 illustrations, the book will be of great interest to graduate students of laser spectroscopy, quantum electronics and quantum optics, and to researchers in these fields.

This book presents the various types of resonance effects on excitons, biexcitons and the local electronic centers (LEC) in solids, such as paramagnetic and paraelectric resonances on excitons, exciton acoustic resonance at intra- and interband transitions, radio-optical double resonance on excitons, hole-nuclear double resonance on localized biexcitons, ENDOR and acoustic ENDOR on LEC. The criteria for the generation of coherent photons, phonons and magnons by excitons are explained. The interactions of excitons and biexcitons with paramagnetic centers and nuclear spins, the indirect interaction between the PC through a field of excitons as well as the quasienergy spectrum of excitons and spin systems are discussed. It is proved that the interactionof paramagnetic centers with excitons increases the spin relaxation rate of paramagneticcenters in comparison with the case of their interaction with free carriers. The giant magneto-opticaleffects in semi-magnetic semiconductors are theoretically interpreted.

In recent years, a new perspective has been added to these systems and their interactions: They can be used for storing and processing information in the form of quantum bits (qubits), the building blocks of quantum computers. The basics of this emerging technology are explained and examples of demonstration-type quantum computers based on localized spins in solids are discussed."
