We introduce a shell model of turbulence featuring intermittent behaviour with anomalous power-law scaling structure functions. This is solved analytically the explicit derivation exponents. The solution associates intermittency hidden symmetry for Kolmogorov multipliers, making our approach relevant real turbulence.

We consider the proton and neutron quasiparticle orbits around the closed-shell (56)Ni and (48)Ca isotopes. It is found that large model spaces (beyond the capability of shell model applications) are necessary for predicting the quenching of spectroscopic factors. The particle-vibration coupling is identified as the principal mechanism. Additional correlations--due to configuration with several...

We investigate the role of symmetry as a possible origin of chaos in the nuclear shell model. For this purpose we disentangle purely geometrical effects due to spin and isospin coupling of the many–body states, from effects of the reduced two– body interaction. We compare a model without symmetry (the embedded two– body ensemble of random matrices) with the two–body random ensemble (TBRE) of th...
