Book Description
Doublement couronné par le prix Nobel en 1997 et en 2001, le domaine des atomes froids est né il y a une trentaine d'années et connaît aujourd'hui un fantastique développement où la physique du solide rejoint la physique atomique. Les atomes froids sont l'objet d'études très fondamentales pour la mécanique quantique et pour l'information quantique. Leurs applications commencent à intervenir dans notre quotidien, par exemple via les horloges à fontaines d'atomes froids utilisées pour le GPS, et dont l'exactitude est meilleure qu'une seconde sur 300 millions d'années. Cet ouvrage expose en termes simples comment l'interaction de faisceaux lasers avec un gaz permet de refroidir ce gaz jusqu'à des températures descendant à quelques millionièmes de degrés au-dessus du zéro absolu et de piéger un petit nuage de quelques milliards d'atomes lévitant dans le vide. Il retrace aussi la découverte de la condensation de Bose-Einstein, ce nouvel état de la matière dans lequel tous les atomes se comportent comme s'ils étaient un seul et dont on peut extraire des « lasers à atomes ». L'ouvrage est illustré de nombreux schémas et présente d'une façon didactique l'essentiel des méthodes utilisées pour produire et utiliser les atomes froids.

Pages : 764
Book Description
Space-based laboratory research in fundamental physics is an emerging research discipline that offers great discovery potential and at the same time could drive the development of technological advances which are likely to be important to scientists and technologists in many other different research fields. The articles in this review volume have been contributed by participants of the international workshop ?From Quantum to Cosmos: Fundamental Physics Research in Space? held at the Airlie Center in Warrenton, Virginia, USA, on May 21?24, 2006. This unique volume discusses the advances in our understanding of fundamental physics that are anticipated in the near future, and evaluates the discovery potential of a number of recently proposed space-based gravitational experiments. Specific research areas covered include various tests of general relativity and alternative theories, search of physics beyond the Standard Model, investigations of possible violations of the equivalence principle, search for new hypothetical long- and short-range forces, variations of fundamental constants, tests of Lorentz invariance and attempts at unification of the fundamental interactions. The book also encompasses experiments aimed at the discovery of novel phenomena, including dark matter candidates, and studies of dark energy.

Book Description
Atomic and molecular physics underlie a basis for our knowledge of fundamental processes in nature and technology and in such applications as solid state physics, chemistry and biology. In recent years, atomic and molecular physics has undergone a revolutionary change due to great achievements in computing and experimental techniques. As a result, it has become possible to obtain information both on atomic and molecular characteristics and on dynamics of atomic and molecular processes. This e-book highlights the present state of investigations in the field of atomic and molecular physics. Recent theoretical developments as well as new discoveries and observations are discussed. the Book should be of interest to students studying atomic and molecular physics and specialists in related fields of science and technology.
Frequency Standards and Metrology

Book Description
The Symposium on Frequency Standards and Metrology is an event held approximately every seven years, and is regarded as the premier conference in the field of advanced clocks and oscillators together with their applications in science and metrology. This series began with the first meeting at Universiteacute; Laval, Quebec Canada in 1971, and the last one was held in 2001 at the University of St. Andrews, Scotland. The 7th Symposium on Frequency Standards and Metrology is scheduled for October 5ndash;11, 2008 at the Asilomar Conference Grounds in Pacific Grove, California, USA. The Symposium is intended as a forum for bringing together international scientists and technologists engaged in the development of precise frequency standards and clocks, the study of their underlying physics, and their applications in metrology and tests of fundamental laws. The symposium has been traditionally held in a venue that promotes exchange of information on emerging ideas and latest achievements in the field, with a single-session approach which includes oral presentations by invitation, poster session(s) and keynote talks from internationally-recognized speakers. The program also includes social and other events aimed at promoting the exchange of technical and scientific information.
