Microscopic description of C+C fusion reactions at nuclear astrophysical energies
K. Nagao, K. Hagino, K. Uzawa
The C + C fusion reaction plays a key role in several astrophysical phenomena. However, it is difficult to determine its cross sections in the relevant energy region…
Determination of nuclear deformations with an emulator for sub-barrier fusion reactions
Zehong Liao, K. Hagino, Long Zhu +2
Based on the eigenvector continuation, which is mathematically an instance of the reduced basis method (RBM), we construct an emulator for coupled-channels calculations for heavy-i…
Re-examination of fusion hindrance in astrophysical C+C and C+C reactions
Kotaro Uzawa, Kouichi Hagino
To determine the energy dependence of fusion cross sections at extremely low energies is crucial for various astrophysical processes. In the previous study by Jiang et al. [Phys. R…
Emulating multi-channel scattering based on the eigenvector continuation in the discrete basis formalism
K. Hagino, Zehong Liao, S. Yoshida +2
We construct an emulator for a multi-channel scattering problem based on the eigenvector continuation. To this end, we employ the Kohn variational principle formulated in the discr…
A microscopic calculation of fission cross sections with the non-equilibrium Green function method
K. Uzawa, K. Hagino
We apply the non-equilibrium Green function (NEGF) method to microscopically evaluate fission cross sections for the neutron induced U reaction. While the model spac…
