An exactly solvable spin chain related to Hahn polynomials
We study a linear spin chain which was originally introduced by Shi et al [1], for which the coupling strength contains a parameter α and depends on the parity of the chain site. Extending the model by a second parameter β, it is shown that the single fermion eigenstates of the Hamiltonian can be computed in explicit form. The components of these eigenvectors turn out to be Hahn polynomials wit...
متن کاملSpin Frustration in an Exactly Solvable Ising-heisenberg Diamond Chain
Exact results of a mixed spin-1/2 and spin-1 Ising-Heisenberg diamond chain are obtained applying a generalized decoration-iteration transformation. Depending on the values of external field, exchange parameters and anisotropy there exist six different phases in the ground state of the system. The magnetic order of these phases is briefly described in this work.
متن کاملAn Exactly Solvable Constrained Xxz Chain *
A new family of exactly solvable models is introduced. These models are generalizations of the XXZ chain where the distance among spins up (σ z-basis) cannot be smaller or equal to t (t = 0, 1, 2, ...). The case t = 0 recovers the standard XXZ chain. The coordinate Bethe ansatz is applied and the phase diagram is calculated. Exploring the finite-size consequences of conformal invariance the cri...
متن کاملAlgebraic spin liquid in an exactly solvable spin model.
We have proposed an exactly solvable quantum spin-3/2 model on a square lattice. Its ground state is a quantum spin liquid with a half-integer spin per unit cell. The fermionic excitations, dubbed as "spinons", are gapless with a linear dispersion, while the topological "vison" excitations are gapped. Moreover, these massless fermionic spinon excitations are topologically stable. Thus, this mod...
متن کاملQuasi-Exactly Solvable Systems and Orthogonal Polynomials
This paper shows that there is a correspondence between quasi-exactly solvable models in quantum mechanics and sets of orthogonal polynomials {Pn}. The quantum-mechanical wave function is the generating function for the Pn(E), which are polynomials in the energy E. The condition of quasi-exact solvability is reflected in the vanishing of the norm of all polynomials whose index n exceeds a criti...
