نویسندگان
چکیده
We study normalization problems associated with use of perturbatively correlated ground-states in extended RPA schemes in the context of a specific but typical example. The sensitivity of the results to the amount of 2p2h admixtures to the correlated ground state is also investigated in terms of a modification of the standard perturbative approach.

Collective excitations in simple metal systems can be described successfully in terms of a local one-body excitation operator Q, due to the long range nature of the coulomb interaction. For the plasmon modes of a simple-metal slab, momentum expansions of Q are calculated using a variational procedure, equivalent to a restricted RPA calculation. The dispersion relation and the density fluctuatio...

We study glueball and meson scattering in compact QED2+1 gauge theory in a Hamiltonian formulation and on a momentum lattice. We compute ground state energy and mass, and introduce a compact lattice momentum operator for the computation of dispersion relations. Using a non-perturbative time-dependent method we compute scattering cross sections for glueballs and mesons. We compare our results wi...

The breathing-mode giant monopole resonance is studied within the framework of the rel-ativistic mean-field (RMF) theory. Using a broad range of parameter sets, a systematic analysis of constrained incompressibility and excitation energy of isoscalar monopole states in finite nuclei is performed. A comparison is made with the incompressibility derived from the semi-infinite nuclear matter and w...

The Skyrme-Hartree-Fock-Bogoliubov code HFBTHO using the axial (2D) Transformed Harmonic Oscillator basis is tested against the HFODD (3D Cartesian HO basis) and HFBRAD (radial coordinate) codes. Results of large-scale ground-state calculations are presented for the SLy4 and SkP interactions.

Using a three-baryon ΛNN potential having a spin-independent dispersive and a two-pion exchange components, realistic variational Monte Carlo calculations have been performed for the Λ-seperation energy for ΛHe. A relationship between strengths associated with both pieces of ΛNN force giving exact experimental Λ-seperation energy has been obtained which then combined with our previous study on ...
