Molecular Spectra from Rotationally Invariant Hamiltonians Based on the Quantum Algebra SUq(2) and Irreducible Tensor Operators under SUq(2)
Dennis Bonatsos, B. A. Kotsos, P. P. Raychev +1
The rotational invariance under the usual physical angular momentum of the SUq(2) Hamiltonian for the description of rotational molecular spectra is explicitly proved and a connect…
Nuclear Moments and Electron Density Functionals in Atoms
R. L. Pavlov, P. P. Raychev, V. P. Garistov +2
An electron density functional approach for the calculation of the nuclear multipole moments is presented. The electronic matrix elements entering the experimentally observed hyper…
Staggering effects in nuclear and molecular spectra
D. Bonatsos, N. Karoussos, C. Daskaloyannis +5
It is shown that the recently observed Delta J = 2 staggering effect (i.e. the relative displacement of the levels with angular momenta J, J+4, J+8, ..., relatively to the levels w…
Quantum algebraic symmetries in atomic clusters, molecules and nuclei
D. Bonatsos, N. Karoussos, P. P. Raychev +1
Quantum algebras (also called quantum groups) are deformed versions of the usual Lie algebras, to which they reduce when the deformation parameter q is set equal to unity. From the…
Symmetries in nuclei and molecules
Dennis Bonatsos, P. Kolokotronis, D. Lenis +6
Recent progress in two different fronts is reported. First, the concept of bisection of a harmonic oscillator (HO) or hydrogen atom (HA), used in the past in establishing the conne…
