Regularities of Many-body Systems Interacting by a Two-body Random Ensemble
Y. M. Zhao, A. Arima, N. Yoshinaga
The ground states of all even-even nuclei have angular momentum, , equal to zero, I=0, and positive parity, . This feature was believed to be a consequence of the attractiv…
Pairing effect on the giant dipole resonance width at low temperature
Nguyen Dinh Dang, Akito Arima
The width of the giant dipole resonance (GDR) at finite temperature T in Sn-120 is calculated within the Phonon Damping Model including the neutron thermal pairing gap determined f…
Modified Hartree-Fock-Bogoliubov at finite temperature
Nguyen Dinh Dang, Akito Arima
The modified HFB (MHFB) theory at finite temperature is derived, which conserves the unitarity relation of the particle-density matrix. This is achieved by constructing a modified…
General pairing interactions and pair truncation approximations for fermions in a single-j shell
Y. M. Zhao, A. Arima, J. N. Ginocchio +1
We investigate Hamiltonians with attractive interactions between pairs of fermions coupled to angular momentum J. We show that pairs with spin J are reasonable building blocks for…
Angular momentum I ground state probabilities of boson systems interacting by random interactions
Y. M. Zhao, A. Arima, N. Yoshinaga
In this paper we report our systematic calculations of angular momentum ground state probabilities () of boson systems with spin in the presence of random two-body in…
Generalization of the scheme to non-yrast levels of even-even nuclei
Y. M. Zhao, A. Arima
In this paper we present the systematics of excitation energies for even-even nuclei in two regions: the 50Z66, 82N104 region, and the 66Z82, 82N104 r…
