Dynamical response functions in correlated fermionic systems
P. Bozek, J. Margueron, H. Muther
Response functions in nuclear matter at finite temperature are considered beyond the usual Hartree-Fock (HF) plus Random Phase Approximation (RPA) scheme. The contributions due to…
Correlations in Hot Asymmetric Nuclear Matter
T. Frick, H. Müther, A. Rios +2
The single-particle spectral functions in asymmetric nuclear matter are computed using the ladder approximation within the theory of finite temperature Green's functions. The inter…
A symmetry-projected variational approach to the 1-dimensional Hubbard-model
K. W. Schmid, T. Dahm, J. Margueron +1
We apply a variational method devised for the nuclear many--body problem to the 1-dimensional Hubbard--model with nearest neighbor hopping and periodic boundary conditions. The tes…
Correlated nucleons in configuration space
H. Müther, Ingo Sick
Several recent studies have dealt with the effects of short range correlations on the momentum distribution of nucleons in nuclei. Here we investigate the correlation effects on th…
Correlations and spectral functions in asymmetric nuclear matter
Kh. S. A. Hassaneen, H. Müther
The self-energy of nucleons in asymmetric nuclear matter is evaluated employing different realistic models for the nucleon-nucleon interaction. Starting from the Brueckner Hartree…
Spectral function at high missing energies and momenta
T. Frick, Kh. S. A. Hassaneen, D. Rohe +1
The nuclear spectral function at high missing energies and momenta has been determined from a self-consistent calculation of the Green's function in nuclear matter using realistic…
