Partial dynamical symmetry in quantum Hamiltonians with higher-order terms
J. E. Garcia-Ramos, A. Leviatan, P. Van Isacker
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…

Symmetries at and Near Critical Points of Quantum Phase Transitions in Nuclei
A. Leviatan, F. Iachello
We examine several types of symmetries which are relevant to quantum phase transitions in nuclei. These include: critical-point, quasidynamical, and partial dynamical symmetries.

Supersymmetric structure in the Dirac equation with cylindrically-deformed potentials
A. Leviatan
Classes of relativistic symmetries accommodating supersymmetric patterns are considered for the Dirac Hamiltonian with axially-deformed scalar and vector potentials.
