Scaling properties of the pairing problem in the strong coupling limit
M. B. Barbaro, R. Cenni, A. Molinari +1
We study the excited states of the pairing Hamiltonian providing an expansion for their energy in the strong coupling limit. To assess the role of the pairing interaction we apply…
Static properties of nuclear matter within the Boson Loop Expansion
W. M. Alberico, R. Cenni, G. Garbarino +1
The use of the Boson Loop Expansion is proposed for investigating the static properties of nuclear matter. We explicitly consider a schematic dynamical model in which nucleons inte…
On the stability of Quantum Hadro-Dynamics
M. B. Barbaro, R. Cenni, M. R. Quaglia
We explore the possible occurrence of - condensation in the Quantum Hadro-Dynamics (QHD), namely the Serot and Walecka model, finding that at the mean field level it correspo…
Bosonization of the Pairing Hamiltonian
Maria B. Barbaro, Maria R. Quaglia
We address the problem of the bosonization of finite fermionic systems with two different approaches. First we work in the path integral formalism, showing how a truly bosonic effe…
The generalised relativistic Lindhard functions
M. B. Barbaro, R. Cenni, M. R. Quaglia
We present here analytic expressions for the generalised Lindhard function, also referred to as Fermi Gas polarisation propagator, in a relativistic kinematic framework and in the…
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…
