M. Alexandre Biguet (Institut de physique nucléaire de Lyon (IPNL))18/11/2014 09:45Théorie et modèles nucléairesLa propriété de liberté asymptotique de la chromodynamique quantique (QCD) fait que ses phases hautes densités et hautes températures sont dominées par les partons (les quarks et les gluons), plutôt que par les hadrons. Le modèle Nambu--Jona-Lasinio (NJL) est un modèle effectif de la QCD considérant les quarks comme degrés de libertés fondamentaux, les gluons étant, eux, gelés. Ce modèle...Go to contribution page

M. Mateo Valdes (IPHC)18/11/2014 10:15Théorie et modèles nucléairesPlusieurs projets lies a la production et a l'utilisation des atomes d'antihydrogµene sont actuelle- ment en cours au CERN [1, 2, 3]. Ces atomes permettent notamment d'etudier de nombreux aspects de l'antimatiere. Dans ce contexte, le projet GBAR (Gravitational Behaviour of Anti- hydrogen at Rest) se propose de realiser pour la premiere fois, un test du principe d'equivalence avec de...Go to contribution page

M. Hongliang LÜ (GANIL and Normandie University)18/11/2014 11:15Théorie et modèles nucléairesOne of the biggest challenges in nuclear physics is to synthesize new super-heavy elements (SHE) and thus to extend the periodic table. It is commonly known that SHE cannot be found in nature. According the shell model, they have been predicted to exist thanks to a regain of stability. Experimentally, by making use of heavy-ion collisions, SHE can be artificially produced in...Go to contribution page

Mlle Irene DEDES (IPHC)19/11/2014 16:15Théorie et modèles nucléairesNeutron stars are the cold, dead remnants of the gravitational collapse of massive stars that ended their lives in violent supernova explosions. With a mass around 1.5{2 times the mass of our Sun packed within a typical radius of about 10 km, neutron stars are among the most compact objects in the universe. This makes neutron stars unique natural laboratories for testing the physical...Go to contribution page

M. Pierre BECKER (IPNL)19/11/2014 16:45Théorie et modèles nucléairesThe possibility of adding a D-wave term to the standard Skyrme effective interaction has beenalready considered in the past. Such a term has been shown to appear in the next-to-next-to-leading order of the Skyrme pseudo-potential. We developed the necessary tools to incorporate this term in a fitting procedure: first, a mean-field equation written in spherical symmetry in order to describe...Go to contribution page

M. Jiajie LI (IPN, Orsay)19/11/2014 17:15Théorie et modèles nucléairesThe formation of new shell gaps in neutron-rich nuclei are investigated within relativistic Hartree-Fock-Bogoliubov theory and the role of Lorentz tensor is studied in detail. We show that the global variation of the single-particle energy is due to the isoscalar component of the effective Lagrangian, while the characteristic behavior of the spin-orbit partner or pseudo-spin partner is due to...Go to contribution page
