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 $T$ -matrices for quantum Poincaré groups: contractions and quantum reference frames

Angel Ballesteros, Diego Fernandez-Silvestre, Ivan Gutierrez-Sagredo

Universal $T$ -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…
