Physics of nuclei: Key role of an emergent symmetry
T. Dytrych, K. D. Launey, J. P. Draayer +6
Exact symmetry and symmetry-breaking phenomena play a key role in providing a better understanding of the physics of many-particle systems, from quarks and atomic nuclei, to molecu…
An equations-of-motion approach to quantum mechanics: application to a model phase transition
S. Y. Ho, G. Rosensteel, D. J. Rowe
We present a generalized equations-of-motion method that efficiently calculates energy spectra and matrix elements for algebraic models. The method is applied to a 5-dimensional qu…
SU(3) density matrix theory
Ts. Dankova, G. Rosensteel
The irreducible representations of the Lie algebra (3) describe rotational bands in the context of the nuclear shell and interacting boson models. The density matrices…
Gauge theory of Riemann ellipsoids
G. Rosensteel, J. Troupe
The classical theory of Riemann ellipsoids is formulated naturally as a gauge theory based on a principal G-bundle . The structure group G=SO(3) is the vorticity group, a…
Triaxial bifurcations of rapidly rotating spheroids
Ts. Dankova, G. Rosensteel
A rotating system, such as a star, liquid drop, or atomic nucleus, may rotate as an oblate spheroid about its symmetry axis or, if the angular velocity is greater than a critical v…
Algebraic mean field theory
Ts. Dankova, G. Rosensteel
Mean field theory has an unexpected group theoretic mathematical foundation. Instead of representation theory which applies to most group theoretic quantum models, Hartree-Fock and…
