Two-component quantum systems develop fundamental modes in terms of in-phase and out-of phase motion of the subsystems. For the nuclear many-body system the framework of the proton-neutron Interacting Boson Approximation (IBA-2) predicted the latter type of excitations as so-called mixed symmetry states. The experimental fingerprint is a strong M1 transition to the proton-neutron symmetric...
Nuclei in the region of the nuclear chart between Z = 28 and 50 magic numbers show a collective behavior that can be attributed to the appearance of quadrupole shape mixing and/or coexistence. Advanced energy density functional (EDF) methods, including symmetry restorations and axial and triaxial shape mixing, are the perfect tools to study these phenomena from a microscopic point of view. In...
Extremely large breaking of the symmetry under the spatial inversion (P-violation) is observed in p-wave resonances of medium heavy nuclei[1]. The enhanced P-violating effect is understood as the result of the combination of the interference between neutron scattering amplitudes of P-unfavored neighboring resonances, which is referred to the kinematical enhancement, and the variance of the...
The Generator Coordinate Method (GCM) provides a general framework to give variational solutions to the many-body problem. It is based on the definition of the variational trial wave functions as the linear mixing of different intrinsic configurations defined along the so-called generating coordinates. This beyond-mean-field method can give ground and excitation energies, decay probabilities,...
