1. Beyond mean-field methods: why and how
The mean-field framework: superheavy nuclei
qp spectra
Correlations beyond mean-field by the GCM
projection and configuration mixing
selected applications
systematic calculations of correlations

2. The mean-field method :
Starting point:
The mean-field method :
Skyrme HFB
Pairing with a density-dependent zero range interaction
Solution of the HF equations on a 3D cartesian mesh
(unrestricted nuclear shape)
Lipkin Nogami method to simulate a Variation
after N,Z projection

11. Beyond mean-field
Set of mean-field wave functions depending on axial Q
Projection on N, Z, J:
New wave functions by mixing on q:
with fJ,k (q) determined by minimizing the energy:

12. First step: triaxiality but TRI

13. First step: triaxiality but TRI
Projection of Jz=0 on J=2

14. Projection of Jz=2 on J=2

16. The future: new energy density functional, more directly
derived from bare N-N interaction
(Duguet and Bonche)
new degrees of freedom (triaxiality and
pairing vibrations)
breaking of symmetries
(time reversal invariance) (Bender and Heenen)
