Symmetries and Supersymmetries of the Dirac Hamiltonian with Axially-Deformed Scalar and Vector Potentials
A. Leviatan
We consider several classes of symmetries of the Dirac Hamiltonian in 3+1 dimensions, with axially-deformed scalar and vector potentials. The symmetries include the known pseudospi…

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.
