Critical Point Symmetries in Nuclei
Dennis Bonatsos, D. Lenis, D. Petrellis +2
Critical Point Symmetries (CPS) appear in regions of the nuclear chart where a rapid change from one symmetry to another is observed. The first CPSs, introduced by F. Iachello, wer…
Sequence of Potentials Interpolating between the U(5) and E(5) Symmetries
Dennis Bonatsos, D. Lenis, N. Minkov +2
It is proved that the potentials of the form (with being integer) provide a ``bridge'' between the U(5) symmetry of the Bohr Hamiltonian with a harmonic oscillator pot…
Odd-Even Staggering in Octupole Bands of Actinides and Rare Earths: Systematics of "Beat" Patterns
Dennis Bonatsos, C. Daskaloyannis, S. B. Drenska +4
``Beat'' patterns are shown to appear in the octupole bands of several actinides and rare earths, their appearance being independent from the formula used in order to isolate and d…
Quantum Groups and Their Applications in Nuclear Physics
Dennis Bonatsos, C. Daskaloyannis
Quantum algebras are a mathematical tool which provides us with a class of symmetries wider than that of Lie algebras, which are contained in the former as a special case. After a…
Simplified boson realization of the subalgebra of and matrix elements of quadrupole operators
P. P. Raychev, R. P. Roussev, P. A. Terziev +2
A simplified boson realization of the subalgebra of is constructed. A simplified form of the corresponding basis states is obtained. The reduced matrix…
Symmetries of anisotropic harmonic oscillators with rational ratios of frequencies and their relations to U(N) and O(N+1)
Dennis Bonatsos, C. Daskaloyannis, P. Kolokotronis +1
The concept of bisection of a harmonic oscillator or hydrogen atom, used in the past in establishing the connection between U(3) and O(4), is generalized into multisection (trisect…
