  • An Exactly Solvable Spin Chain Related to Hahn Polynomials 
    Stoilova, N.I.; Van der Jeugt, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    We study a linear spin chain which was originally introduced by Shi et al. [Phys. Rev. A 71 (2005), 032309, 5 pages], for which the coupling strength contains a parameter α and depends on the parity of the chain site. ...
  • Deformed su(1,1) Algebra as a Model for Quantum Oscillators 
    Jafarov, E.I.; Stoilova, N.I.; Van der Jeugt, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2012)
    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 ...
  • Doubling (Dual) Hahn Polynomials: Classification and Applications 
    Oste, R.; Van der Jeugt, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    We classify all pairs of recurrence relations in which two Hahn or dual Hahn polynomials with different parameters appear. Such couples are referred to as (dual) Hahn doubles. The idea and interest comes from an example ...
