Poincare Seminar 2003 Bose-einstein Condensation, Entropy

This volume contains the third and fourth Poincar? Seminar, both held in 2003. The third one is devoted to Bose-Einstein Condensation: it covers the physics of superfluid liquid helium as well as the recently discovered atomic Bose-Einstein condensates. Major experimental results are presented, together with relevant theoretical approaches and remaining open questions. The fourth one is devoted to Entropy, giving a comprehensive account of the history and various realizations of this concept, from thermodynamics to black holes, and includes theoretical and experimental discussions of the corresponding fluctuations for mesoscopic systems near equilibrium.Dalibard, J. is the author of 'Poincare Seminar 2003 Bose-einstein Condensation, Entropy', published 2004 under ISBN 9780817671167 and ISBN 0817671161.
