Racah's method for general subalgebra chains: Coupling coefficients of SO(5) in canonical and physical bases
M. A. Caprio, K. D. Sviratcheva, A. E. McCoy
It is shown that the method of infinitesimal generators ("Racah's method") can be broadly and systematically formulated as a method applicable to the calculation of reduced couplin…
Evidence for Symplectic Symmetry in Ab Initio No-Core Shell Model Results for Light Nuclei
Tomas Dytrych, Kristina D. Sviratcheva, Chairul Bahri +2
Clear evidence for symplectic symmetry in low-lying states of C and O is reported. Eigenstates of C and O, determined within the framework of the no-cor…
Global Properties of fp-Shell Interactions in Many-nucleon Systems
K. D. Sviratcheva, J. P. Draayer, J. P. Vary
Spectral distribution theory, which can be used to compare microscopic interactions over a broad range of nuclei, is applied in an analysis of two modern effective interactions bas…
Underlying symmetries of realistic interactions and the nuclear many-body problem
K. D. Sviratcheva, J. P. Draayer, J. P. Vary
The present study brings forward important information, within the framework of spectral distribution theory, about the types of forces that dominate three realistic interactions,…
Microscopic Description of Isospin Mixing Pairing Correlations in the Framework of an Algebraic Sp(4) Model
K. D. Sviratcheva, A. I. Georgieva, J. P. Draayer
We explore isospin mixing beyond that due to the Coulomb interaction in the framework of an exactly solvable microscopic sp(4) algebraic approach. Specifically, we focus on the iso…
Isospin symmetry breaking in an algebraic pairing Sp(4) model
K. D. Sviratcheva, A. I. Georgieva, J. P. Draayer
An exactly solvable sp(4) algebraic approach extends beyond the traditional isospin conserving nuclear interaction to bring forward effects of isospin symmetry breaking and isospin…
