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…
Multi- hypernuclei
D. Gazda, E. Friedman, A. Gal +1
Relativistic mean field calculations of multi- hypernuclei are performed by adding mesons to particle-stable configurations of nucleons, and hyperons. For a…
pi^- decay rates of p-shell hypernuclei revisited
Avraham Gal
Explicit expressions for the parity-violating s-wave and the parity-conserving p-wave contributions to pi- weak-decay rates of Lambda hypernuclei in the 1p shell are given in the w…
6He beta-decay rate and the suppression of the axial constant in nuclear matter
Sergey Vaintraub, Nir Barnea, Doron Gazit
We present a microscopic calculation of the 6He beta-decay into the ground state of 6Li. To this end, we use chiral perturbation theory at next-to-next-to-next-to-leading order to…
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.
