Deformed su(1,1) Algebra as a Model for Quantum Oscillators

Abstract: Abstract. The Lie algebra su(1, 1) can be deformed by a reflection operator, in such a way that the positive discrete series representations of su(1, 1) can be extended to representations of this deformed algebra su(1, 1) γ . Just as the positive discrete series representations of su(1, 1) can be used to model a quantum oscillator with Meixner-Pollaczek polynomials as wave functions, the corresponding representations of su(1, 1) γ can be utilized to construct models of a quantum oscillator. In this case, the w… Show more

“…Substantial work has been done on these systems which are now well understood and classified (see [4,37,16,17,18,19,20,21,30] and references therein). Further developments in the study of integrable systems include progress in the classification of superintegrable systems with higher order symmetry [22,38,39], the examination of discrete/finite superintegrable models [25] and the exploration of systems involving reflection operators [7,14,15,27,28,29,31,32,34,35].…”

“…In view of the special properties and applications of superintegrable models, there is considerable interest in enlarging the set of documented systems with this property. Recent advances in this perspective include the study of superintegrable systems with higher order symmetries [25,26,34,50,51], the construction of new superintegrable models from exceptional polynomials [35,42], the search for discretized superintegrable systems [36] and the examination of models described by Hamiltonians involving reflection operators [10,11,21,22,40,41,43,44].…”

“…The Casimir operator of H then takes the form 5) which is clearly a simple one-parameter deformation of the standard sl(2) Casimir operator. Interestingly, one-parameter versions of this algebra (with either ν or χ equal to zero) have been introduced in studies of finite analogues of the parabosonic oscillator 6,7 . The wave functions that were found in this context turn out to be symmetrized dual −1 Hahn polynomials.…”
