Effect of pairing correlations on nuclear low-energy structure: BCS and general Bogoliubov transformation
J. Xiang, Z. P. Li, J. M. Yao +3
Low-lying nuclear states of Sm isotopes are studied in the framework of a collective Hamiltonian based on covariant energy density functional theory. Pairing correlation are treate…
Isovector dipole-resonance structure within the effective surface approximation
J. P. Blocki, A. G. Magner, P. Ring
The nuclear isovector-dipole strength structure is analyzed in terms of the main and satellite (pygmy) peaks within the Fermi-liquid droplet model. Such a structure is sensitive to…
Implementation of the finite amplitude method for the relativistic quasiparticle random-phase approximation
Tamara Niksic, Nenad Kralj, Tea Tutis +2
A new implementation of the finite amplitude method (FAM) for the solution of the relativistic quasiparticle random-phase approximation (RQRPA) is presented, based on the relativis…
Relativistic two-phonon model for low-energy nuclear response
Elena Litvinova, Peter Ring, Victor Tselyaev
A two-phonon version of the relativistic quasiparticle time blocking approximation introduces as a new class of many-body models for nuclear structure calculations based on the cov…
Nuclear shell structure and response toward the limits of mass, temperature and isospin
E. Litvinova, B. A. Brown, D. -L. Fang +4
We present a short overview of our recent theoretical developments aiming at the description of exotic nuclear phenomena to be reached and studied at the next-generation radioactiv…
Pairing strength on the nuclear size in relativistic continuum Hartree-Bogoliubov theory
Ying Chen, Peter Ring, Jie Meng
The influence of pairing correlations on the nuclear size and in particular on the formation of nuclear halos is studied in the framework of relativistic continuum Hartree-Bogoliub…
Application of the inverse Hamiltonian method to Hartree-Fock-Bogoliubov calculations
Y. Tanimura, K. Hagino, P. Ring
We solve the Hartree-Fock-Bogoliubov (HFB) equations for a spherical mean field and a pairing potential with the inverse Hamiltonian method, which we have developed for the solutio…
Nuclear asymmetry energy and isovector stiffness within the effective surface approximation
J. P. Blocki, A. G. Magner, P. Ring +1
The isoscalar and isovector particle densities and the surface tension coefficients at the average binding energy are used to derive analytical expressions of the neutron skin thic…
