Harmonic oscillator chains as Wigner Quantum Systems: periodic and fixed wall boundary conditions in gl(1|n) solutions
S. Lievens, N. I. Stoilova, J. Van der Jeugt
We describe a quantum system consisting of a one-dimensional linear chain of n identical harmonic oscillators coupled by a nearest neighbor interaction. Two boundary conditions are…

The paraboson Fock space and unitary irreducible representations of the Lie superalgebra osp(1|2n)
S. Lievens, N. I. Stoilova, J. Van der Jeugt
It is known that the defining relations of the orthosymplectic Lie superalgebra osp(1|2n) are equivalent to the defining (triple) relations of n pairs of paraboson operators $b^\pm…
