Quantum spin chains with fractional revival

VX Genest, L Vinet, A Zhedanov - Annals of Physics, 2016 - Elsevier
A systematic study of fractional revival at two sites in XX quantum spin chains is presented.
Analytic models with this phenomenon are obtained by combining two basic ways of …

Finite oscillator models: the Hahn oscillator

EI Jafarov, NI Stoilova… - Journal of Physics A …, 2011 - iopscience.iop.org
A new model for the finite one-dimensional harmonic oscillator is proposed based upon the
algebra. This algebra is a deformation of the Lie algebra extended by a parity operator, with …

The Hahn oscillator and a discrete Fourier–Hahn transform

EI Jafarov, NI Stoilova… - Journal of Physics A …, 2011 - iopscience.iop.org
We define the quadratic algebra $\mathfrak {su}(2) _\alpha $ which is a one-parameter
deformation of the Lie algebra $\mathfrak {su}(2) $ extended by a parity operator. The odd …

Dual-1 Hahn polynomials:“classical” polynomials beyond the Leonard duality

S Tsujimoto, L Vinet, A Zhedanov - Proceedings of the American …, 2013 - ams.org
We introduce the $-$1 dual Hahn polynomials through an appropriate $ q\to-1$ limit of the
dual $ q $-Hahn polynomials. These polynomials are orthogonal on a finite set of discrete …

An analytic spin chain model with fractional revival
