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…
