Self-consistent Green’s function method for nuclei and nuclear matter
Recent results obtained by applying the method of self-consistent Green’s functions to nuclei and nuclear matter are reviewed. Particular attention is given to the description of experimental data obtained from the (e,e′p) and (e,e′2N) reactions that determine one and two-nucleon removal probabilities in nuclei since the corresponding amplitudes are directly related to the imaginary parts of th...
متن کاملSelf-consistent Green's function calculations of finite nuclei
The properties of mean field orbits near the Fermi level can be strongly affected by collective excitations of the system. Such mechanisms are expected to have relevant effects on shell closure and spectroscopic factors for nuclei with extreme neutron/proton ratios. The coupling of single particle (sp) motion to excitations of the core, as well as to particle-particle (pp) and hole-hole (hh) co...
متن کاملGorkov self-consistent Green’s function calculations of semi-magic nuclei
The first nuclear structure application of the newly developed Gorkov selfconsistent Green’s function method is presented. The approach aims to describe many-nucleon systems from an ab-initio standpoint featuring an explicit treatment of pairing correlations. In the present work calculations of binding energies of calcium isotopes are reported and compared with experimental data and other theor...

where E PT is the contribution to the total binding energy in second order perturbation theory. A perturbative expansion of the RPA equations shows that (i) the sum in Eq. (1) must also include charge exchange modes and (ii) E PT is double counted and must be subtracted [3]. This leads to an improved description of the binding energies of most closed shell nuclei, up to Pb, as shown in Fig. 1 [...
