Finite-amplitude method: An extension to the covariant density functionals
Haozhao Liang, Takashi Nakatsukasa, Zhongming Niu +1
The finite-amplitude method (FAM) is one of the most promising methods for optimizing the computational performance of the random-phase approximation (RPA) calculations in deformed…
Nuclear charge-exchange excitations in localized covariant density functional theory
H. Z. Liang, J. Meng, T. Nakatsukasa +5
The recent progress in the studies of nuclear charge-exchange excitations with localized covariant density functional theory is briefly presented, by taking the fine structure of s…
Pairing Effects in Nuclear Fusion Reaction
Shuichiro Ebata, Takashi Nakatsukasa
We simulate a heavy-ion collision using the canonical-basis time-dependent Hartree-Fock-Bogoliubov theory (Cb-TDHFB) treating pairing correlation in the three-dimensional coordinat…
Energy-density-functional calculations including the proton-neutron mixing
Koichi Sato, Jacek Dobaczewski, Takashi Nakatsukasa +1
We present results of calculations based on the Skyrme energy density functional including the arbitrary mixing between protons and neutrons. In this framework, single-particle sta…
Low-energy E1 strength in select nuclei: Possible constraints on the neutron skins and the symmetry energy
Tsunenori Inakura, Takashi Nakatsukasa, Kazuhiro Yabana
Correlations between low-lying electric dipole (E1) strength and neutron skin thickness are systematically investigated with the fully self-consistent random-phase approximation us…
Shape evolution of giant resonances in Nd and Sm isotopes
Kenichi Yoshida, Takashi Nakatsukasa
Giant multipole resonances in Nd and Sm isotopes are studied by employing the quasiparticle-random-phase approximation on the basis of the Skyrme energy-density-functional method.…

Y. Fukuoka, S. Shinohara, Y. Funaki +2
We report an investigation of the structure of C nucleus employing a newly developed configuration-mixing method. In the three-dimensional coordinate-space representation, w…
Feasibility of the finite amplitude method in covariant density functional theory
Haozhao Liang, Takashi Nakatsukasa, Zhongming Niu +1
Self-consistent relativistic random-phase approximation (RPA) in the radial coordinate representation is established by using the finite amplitude method (FAM). Taking the isoscala…
Time-dependent density-functional studies on strength functions in neutron-rich nuclei
Shuichiro Ebata, Tsunenori Inakura, Takashi Nakatsukasa
The electric dipole (E1) strength functions have been systematically calculated based on the time-dependent density functional theory (TDDFT), using the finite amplitude method and…
Systematic investigation of E1 strength for the isotopes from Z = 28 to 50
Shuichiro Ebata, Takashi Nakatsukasa, Tsunenori Inakura
We carry out a systematic study of electric dipole mode (E1) for neutron-rich isotopes from nickel (Z=28) to tin (Z=50) using a time-dependent mean-field theory. Our time-dependent…
Efficient calculation for the quasiparticle random-phase approximation matrix
Paolo Avogadro, Takashi Nakatsukasa
We present an efficient numerical technique to evaluate the matrix of the (quasiparticle)-random-phase approximation, using the finite amplitude method (FAM). The method is tested…
