Relativistic Hamiltonians are defined as the sum of relativistic one-body kinetic energies, twoand many-body interactions and their boost corrections. We review the calculation of the boost correction of the two-body interaction from commutation relations of the Poincaré group and show that its important terms can be easily understood from classical relativistic mechanics. The boost corrections...

Based on the formalism of thermo-field dynamics a new approach for studying collective excitations in hot finite Fermi systems is presented. Two approximations going beyond the thermal RPA namely renormalized thermal RPA and thermal second RPA are formulated.

The two-body momentum distribution η 2 (p 1 , p 2) of nuclei is studied. First, a compact analytical expression is derived for Z = N , ℓ-closed nuclei, within the context of the independent particle shell model. Application to the light closed-shell nucleus 16 O is included and discussed. Next, the effect of dynamical, short-range correlations is investigated in the case of the light nucleus 4 ...
