An exactly solvable supersymmetric spin chain of BC_N type
J. C. Barba, F. Finkel, A. Gonzalez-Lopez +1
We construct a new exactly solvable supersymmetric spin chain related to the BC_N extended root system, which includes as a particular case the BC_N version of the Polychronakos-Fr…
A novel quasi-exactly solvable spin chain with nearest-neighbors interactions
A. Enciso, F. Finkel, A. Gonzalez-Lopez +1
In this paper we study a novel spin chain with nearest-neighbors interactions depending on the sites coordinates, which in some sense is intermediate between the Heisenberg chain a…
Exchange operator formalism for N-body spin models with near-neighbors interactions
A. Enciso, F. Finkel, A. Gonzalez-Lopez +1
We present a detailed analysis of the spin models with near-neighbors interactions constructed in our previous paper [Phys. Lett. B 605 (2005) 214] by a suitable generalization of…
Solvable scalar and spin models with near-neighbors interactions
A. Enciso, F. Finkel, A. Gonzalez-Lopez +1
We construct new solvable rational and trigonometric spin models with near-neighbors interactions by an extension of the Dunkl operator formalism. In the trigonometric case we obta…
