Analytical Bethe Ansatz for closed and open gl(M|N) super-spin chains in arbitrary representations and for any Dynkin diagram
E. Ragoucy, G. Satta
We present the analytical Bethe ansatz for spin chains based on the superalgebras gl(M|N), , with at each site an arbitrary representation (and including inhomogeneities).…
A rigid body dynamics derived from a class of extended Gaudin models : an integrable discretization
F. Musso, M. Petrera, O. Ragnisco +1
We consider a hierarchy of classical Liouville completely integrable models sharing the same (linear) --matrix structure obtained through an --th jet--extension of $\mathfrak…
Gaudin models with ${\CU}_q(\mathfrak{osp}(1 | 2))$ symmetry
Fabio Musso, Matteo Petrera, Orlando Ragnisco +1
We consider a Gaudin model related to the q-deformed superalgebra ${\CU}_q(\mathfrak{osp}(1 | 2))$. We present an exact solution to that system diagonalizing a complete set of comm…
Bäcklund transformations for the rational Lagrange chain
Fabio Musso, Matteo Petrera, Orlando Ragnisco +1
We consider a long--range homogeneous chain where the local variables are the generators of the direct sum of interacting Lagrange tops. We call this classica…
