Dynamical symmetries of generalized Taub-NUT and multi-center metrics
J. -P. Ngome
Hidden symmetries of generalized Kaluza-Klein-type metrics are studied using van Holten's systematic analysis \cite{vH} based on Killing tensors. Applied to generalized Taub-NUT me…
(Super)symmetries of semiclassical models in theoretical and condensed matter physics
J. -P. Ngome
Van Holten's covariant algorithm for deriving conserved quantities is presented, with particular attention paid to Runge-Lenz-type vectors. The classical dynamics of isospin-carryi…
Non-commutative oscillator with Kepler-type dynamical symmetry
P. M. Zhang, P. A. Horvathy, J. -P. Ngome
A 3-dimensional non-commutative oscillator with no mass term but with a certain momentum-dependent potential admits a conserved Runge-Lenz vector, derived from the dual description…
Dynamical supersymmetry of spin particle-magnetic field interaction
J. -P. Ngome, P. A. Horváthy, J. W. van Holten
We study the super and dynamical symmetries of a fermion in a monopole background. The Hamiltonian also involves an additional spin-orbit coupling term, which is parameterized by t…
Conserved quantities in non-abelian monopole fields
P. A. Horvathy, J. -P. Ngome
Van Holten's covariant Hamiltonian framework is used to find conserved quantities for an isospin-carrying particle in a non-Abelian monopole-like field. For a Wu-Yang monopole we f…
