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…
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…
Haldane-Shastry spin chains of BC_N type
A. Enciso, F. Finkel, A. Gonzalez-Lopez +1
We introduce four types of SU(2M+1) spin chains which can be regarded as the BC_N versions of the celebrated Haldane-Shastry chain. These chains depend on two free parameters and,…
