From Quantum Universal Enveloping Algebras to Quantum Algebras
E. Celeghini, A. Ballesteros, M. A. del Olmo
The ``local'' structure of a quantum group G_q is currently considered to be an infinite-dimensional object: the corresponding quantum universal enveloping algebra U_q(g), which is…
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…
Solutions for the constant quantum Yang-Baxter equation from Lie (super)algebras
A. Tanasa, A. Ballesteros, F. J. Herranz
We present a systematic procedure to obtain singular solutions of the constant quantum Yang-Baxter equation in arbitrary dimension. This approach, inspired in the Lie (super)algebr…
