  1. Phase transition and frustration in nuclear physic and astrophysic. Les jeunots en physique nucléaire de basse énergie. On fait quoi ? Comment ? Karim Hasnaoui(1) Phd Supervisors : Ph.

  2. Classical Approaches : LGM & RG. • LGM (Lattice Gas Model) for star matter : • Liquid-gas phase transition. • Suppression of critical point. PRL98, 131102 (2007). PRC75, 65805 (2007). • RG (Renormalisation Group) : • Mixe short and long range interaction  Critical Phenomena ?

  3. Quantum Approach : FMD. • Ingredients of FMD (Fermionic molecular dynamics) : • Antisymetrisation of gaussian wave packet. • Realistic interaction : Skyrme force. • Nuclear thermometer. • Thermodynamics : • Caloric curve of finite nuclei. • Treat the quantum probleme for star matter. • Nuclear Structure : • Ground State. • Giant resonance  GMR of light nuclei.
