Partial dynamical symmetry and the vibrational structure of Cd isotopes
Leviatan, A.; Gavrielov, N.; García Ramos, José Enrique
; Van Isacker, P. (EDP Sciences, 2018)
The recently reported deviations of selected non-yrast states in 110Cd from the expected sphericalvibrator behaviour, is addressed by means of an Hamiltonian with U(5) partial dynamical symmetry. The latter preserves the ... -
Partial dynamical symmetry as a selection criterion for many-body interactions
Leviatan, A.; García Ramos, José Enrique; Van Isacker, P. (American Physical Society, 2013)
We propose the use of partial dynamical symmetry (PDS) as a selection criterion for higher-order terms in situations when a prescribed symmetry is obeyed by some states and is strongly broken in others. The procedure is ... -
Partial dynamical symmetry in quantum Hamiltonians with higher-order terms
García Ramos, José Enrique; Leviatan, A.; Van Isacker, P. (American Physical Society, 2009-03-20)
A generic procedure is proposed to construct many-body quantum Hamiltonians with partial dynamical symmetry. It is based on a tensor decomposition of the Hamiltonian and allows the construction of a hierarchy of interactions ... -
Quadrupole phonons in the cadmium isotopes
Leviatan, A.; Gavrielov, N.; García Ramos, José Enrique; Van Isacker, P. (American Physical Society, 2018)
A key question concerning the spherical-vibrator attributes of states in cadmium isotopes is addressed by means of a boson Hamiltonian encompassing U(5) partial dynamical symmetry. The U(5) symmetry is preserved in a segment ...
