Next-nearest-neighbor spin-spin and chiral-spin correlation functions in generalized XXX chain
V. V. Mkhitaryan, A. G. Sedrakyan
We develop a simple technique for calculation of next to nearest neighbor spin-spin and chiral-spin correlation functions in inhomogeneous XXX model. Exact expression of the chiral…

Fermionisation of the Spin-S Uimin-Lai-Sutherland Model: Generalisation of Supersymmetric t-J Model to Spin-S
J. Ambjorn, D. Karakhanyan, M. Mirumyan +1
The spin-1 Uimin-Lai-Sutherland (ULS) isotropic chain model is expressed in terms of fermions and the equivalence of the fermionic representation to the supersymmetric t-J model is…
