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…

Effects of ground-state correlations on damping of giant dipole resonaces in closed shell nuclei

Mitsuru Tohyama

The effects of ground-state correlations on the damping of isovector giant dipole resonances in closed shell nuclei O and Ca are studied using extended random-ph…

Effects of ground-state correlations on magnetic dipole excitations in Ca

Mitsuru Tohyama

The effects of ground-state correlations on the magnetic dipole excitations in Ca are studied using an extended random phase approximation (ERPA) derived from the time-depen…

Is perturbative study of ground-state correlations valid?

Mitsuru Tohyama

Perturbative approaches have often been used to include the effects of ground-state correlations in extended theories of the random-phase approximation. Validity of such approaches…
