Description
Workshop on experimental and theoretical approaches to quantum states of neutrons in gravitational field. The aim of this workshop is to discuss the scientific program with new GRANIT spectrometer in a broad context of behavior of ultracold neutrons (UCN) in gravitational field in GRANIT and in alternative experiments, as well as applications of this phenomenon/spectrometer to various domains of physics, ranging from short-range interactions to neutron quantum optics and reflectometry using UCN. Topics will be the scientific issues, instrumental and methodical developments, alternative methods, new ideas. It is a follow-up for the GRANIT-2006 Workshop (http://lpsc.in2p3.fr/congres/granit06/index.php), and preceding Annual meetings of the collaboration on measurement of the quantum states of neutrons in the gravitational field. The registration fee will be payed in "Les Houches" by credit card (no american express), cheque or in cash (cost : 450 euros) Organizing Committee Stefan Baessler, University of Virginia, USA Orfeu Bertolami, Instituto Superior Tecnico, Lisbon, Portugal Dirk Dubbers, Heidelberg University, Germany Alexander Meyerovich, University of Rhode Island, USA Valery Nesvizhevsky, Institut Laue-Langevin, Grenoble, France Konstantin Protasov, Laboratoire de Physique Subatomique et de Cosmologie, Grenoble, France Philipp Schmidt-Wellenburg, PSI, Switzeland Serge Reynaud, Laboratoire Kastler Brossel, Paris, France
