Hamiltonian reduction from particular integrals
R. Azuaje, A. M. Escobar-Ruiz, I. Gutierrez-Sagredo
We develop a geometric reduction mechanism generated by systems of particular integrals, namely, families of functions whose time derivatives close linearly on the family. Their co…
The Fock-Darwin-Darboux system: eigenstates, information entropies and dispersion-like measures
Ignacio Baena-Jimenez, Angel Ballesteros, Ivan Gutierrez-Sagredo
The Fock-Darwin (FD) quantum system describes the motion on the plane of a charged particle under the action of an isotropic oscillator potential together with a perpendicular cons…
Universal -matrices for quantum Poincaré groups: contractions and quantum reference frames
Angel Ballesteros, Diego Fernandez-Silvestre, Ivan Gutierrez-Sagredo
Universal -matrices, or Hopf algebra dual forms, for quantum groups are revisited, and their contraction theory is developed. As a first illustrative example, the (1+1) timelike…
