Limited-angle SPECT image reconstruction using deep image prior
Kensuke Hori, Fumio Hashimoto, Kazuya Koyama +1
In SPECT image reconstruction, limited-angle (LA) conditions lead to a loss of frequency components, which distort the reconstructed tomographic image along directions correspondin…
Number conservation in odd-particle number random phase approximation and extensions
Mitsuru Tohyama
The number conservation law in the odd-particle number random-phase approximation (oRPA) and its extension (EoRPA) is studied by applying them to a pairing model and O. It i…
Extended random-phase-approximation study of fragmentation of giant quadrupole resonance in O
Mitsuru Tohyama
The damping of isoscalar giant quadrupole resonance in O is studied using extended random-phase-approximation approaches derived from the time-dependent density-matrix theor…
Properties of Skyrme force as a residual interaction in beyond mean-field theories
Mitsuru Tohyama
In an effort to find an effective interaction which can consistently be used for both the mean-field part and the residual part in beyond mean-field theories, properties of the Sky…
Equation of Motion Method to strongly correlated Fermi systems and Extended RPA approaches
P. Schuck, D. S. Delion, J. Dukelsky +4
The status of different extensions of the Random Phase Approximation (RPA) is reviewed. The general framework is given within the Equation of Motion Method and the equivalent Green…
Truncation scheme of time-dependent density-matrix approach III
Mitsuru Tohyama, Peter Schuck
The time-dependent density-matrix theory (TDDM) where the Bogoliubov-Born-Green-Kirkwood-Yvon hierarchy for reduced density matrices is truncated by approximating a three-body dens…
