Collective excitations and energy-weighted sum rules in relativistic random phase approximation with vacuum polarization
A. Haga, H. Toki, S. Tamenaga +1
The isoscalar and isovector collective multipole excitations in stable nuclei are studied in the framework of relativistic random-phase approximation with the vacuum polarization a…

Self-consistent relativistic random phase approximation with vacuum polarization
A. Haga, H. Toki, S. Tamenaga +2
We present a theoretical formulation for the description of nuclear excitations within the framework of relativistic random-phase approximation whereby the vacuum polarization aris…

Relativistic Hartree approach with exact treatment of vacuum polarization for finite nuclei
Akihiro Haga, Setsuo Tamenaga, Hiroshi Toki +1
We study the relativistic Hartree approach with the exact treatment of the vacuum polarization in the Walecka sigma-omega model. The contribution from the vacuum polarization of nu…
