La 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...

Plusieurs 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...

One 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...

Neutron 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...

The 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...

The 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...
