Coherent and Collective Interactions of Particles and Radiation Beams: Varenna on Lake Como, Villa Monastero, 11-21 July 1995

Abstract

This work focuses on fundamental theoretical and experimental aspects of relativistic beam physics, recoil, and cooling phenomena in atomic and ion beams and traps, emphasizing coherence and collective effects. The physics of atomic laser and free electron laser, and the development of a bridge between them through the mechanism of the so-called recoil induced gain mechanism, is also examined, as are the links between relativistic beam physics and atomic laser physics. Topics include: laser cooling of trapped ions; optical lattices; spatio-temporal instabilities in optical systems; coherence in atom optics; coherent population trapping; two-level gain and collective recoil-induced effects; high-gain free electron laser - theory, experiments and projects; cooling of ion beams in a storage ring; and experiments on dense laser-cooled stored ion beams.

The goal of this volume is to discuss the rapidly moving field of atom optics and interferometry with all its intricate aspects ranging from fundamental physics to applications and the theory of relativity. The breathtaking success in manipulating atoms using lasers has encouraged these two so far disjunct communities to move closer together and begin collaborations. After an introduction to atom optics and Bose-Einstein condensation, the theoretical foundations of cold atom interferometers, their use to test gravity, and their implementation in laboratory measurements of the earth rotation and of Newton's gravitational constant are discussed. Several papers discuss the characteristics of gyroscopes and interferometers as sensors for inertial forces, starting from gyroscopes based on light waves and comparing their sensitivity to those based on matter waves. The final topic is the variation of fundamental constants, a subject that during the last years has attracted a lot of attention from different communities of physics.
