The q-deformed Haldane-Shastry model
Didina SERBAN
( I PhT CEA Saclay et LPTM CY CPU )
The Haldane-Shastry chain is an unique example among the long-range integrable spin chains, possessing Yangian symmetry for any length.
More than twenty years ago, a XXZ-like deformation of the Haldane-Shastry model was also proposed, where the Yangian symmetry is replaced by quantum affine symmetry. In a recent work with Jules Lamers and Vincent Pasquier we have succeeded to give a explicit construction of the highest
weight vectors in terms of Macdonald polynomials. In the talk I will report on these results I will comment on some open problems.
