Robustness of the proxy-SU(3) symmetry in atomic nuclei and the role of the next highest weight irreducible representation
Dennis Bonatsos, Andriana Martinou, S. K. Peroulis +4
The proxy-SU(3) symmetry predicts, in a parameter-free way, the collective deformation variables beta and gamma in even-even atomic nuclei away from closed shells based on the high…

Preponderance of triaxial shapes in atomic nuclei predicted by the proxy-SU(3) symmetry
Dennis Bonatsos, Andriana Martinou, S. K. Peroulis +4
The proxy-SU(3) symmetry predicts, in a parameter-free way, based only on the Pauli principle and the short-range nature of the nucleon-nucleon interaction, non-vanishing values of…

Mean-field derived IBM-1 Hamiltonian with intrinsic triaxial deformation
Polytimos Vasileiou, Dennis Bonatsos, Theo J. Mertzimekis
An interacting-boson-model-1 (IBM-1) Hamiltonian, derived from self-consistent mean-field calculations using a Skyrme energy density functional is employed for the study of energy…
