Continuous and Discrete (Classical) Heisenberg Spin Chain Revised

Ragnisco, O.; Zullo, F. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)

Most of the work done in the past on the integrability structure of the Classical Heisenberg Spin Chain (CHSC) has been devoted to studying the su(2) case, both at the continuous and at the discrete level. In this paper ...
From su(2) Gaudin Models to Integrable Tops

Petrera, M.; Ragnisco, O. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)

In the present paper we derive two well-known integrable cases of rigid body dynamics (the Lagrange top and the Clebsch system) performing an algebraic contraction on the two-body Lax matrices governing the (classical) ...
Quantum Deformations and Superintegrable Motions on Spaces with Variable Curvature

Ragnisco, O.; Ballesteros, A.; Herranz, F.J.; Musso, F. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)

An infinite family of quasi-maximally superintegrable Hamiltonians with a common set of (2N-3) integrals of the motion is introduced. The integrability properties of all these Hamiltonians are shown to be a consequence of ...
