Mean field at finite temperature and symmetry breaking
A. Beraudo, A. De Pace, M. Martini +1
For an infinite system of nucleons interacting through a central spin-isospin schematic force we discuss how the Hartree-Fock theory at finite temperature T yields back, in the T=0…
The many levels pairing Hamiltonian for two pairs
M. B. Barbaro, R. Cenni, A. Molinari +1
We address the problem of two pairs of fermions living on an arbitrary number of single particle levels of a potential well (mean field) and interacting through a pairing force. Th…
The Goldstone bosons in the pairing Hamiltonian: the path integral approach
M. B. Barbaro, A. Molinari, F. Palumbo +1
As a first step to derive the IBM from a microscopic nuclear hamiltonian, we bosonize the pairing hamiltonian in the framework of the path integral formalism respecting both the pa…
Nuclear response functions for the N-N*(1440) transition
L. Alvarez-Ruso, M. B. Barbaro, T. W. Donnelly +1
Parity-conserving and -violating response functions are computed for the inclusive electroexcitation of the N*(1440)(Roper) resonance in nuclear matter modeled as a relativistic Fe…
Delta-isobar relativistic meson exchange currents in quasielastic electron scattering
J. E. Amaro, M. B. Barbaro, J. A. Caballero +2
We study the role of the -isobar current on the response functions for high energy inclusive quasielastic electron scattering from nuclei. We consider a general Lagrangian which…
