Twisted (2+1) -AdS Algebra, Drinfel'd Doubles and Non-Commutative Spacetimes
Ángel Ballesteros, Francisco J. Herranz, Catherine Meusburger +1
We construct the full quantum algebra, the corresponding Poisson-Lie structure and the associated quantum spacetime for a family of quantum deformations of the isometry algebras of…
A (2+1) non-commutative Drinfel'd double spacetime with cosmological constant
Angel Ballesteros, Francisco J. Herranz, Catherine Meusburger
We show that the Drinfel'd double associated to the standard quantum deformation is isomorphic to the (2+1)-dimensional AdS algebra with the initial deformation paramet…
A maximally superintegrable deformation of the N-dimensional quantum Kepler-Coulomb system
Angel Ballesteros, Alberto Enciso, Francisco J. Herranz +2
The -dimensional quantum Hamiltonian is shown to be exa…
Effective su_q(2) models and polynomial algebras for fermion-boson Hamiltonians
Angel Ballesteros, Osvaldo Civitarese, Francisco J. Herranz +1
Schematic su(2)+h3 interaction Hamiltonians, where su(2) plays the role of the pseudo-spin algebra of fermion operators and h3 is the Heisenberg algebra for bosons, are shown to be…
