N=2 Hamiltonians with sl(2) coalgebra symmetry and their integrable deformations
A. Ballesteros, O. Ragnisco
Two dimensional classical integrable systems and different integrable deformations for them are derived from phase space realizations of classical Poisson coalgebras and th…

Long range integrable oscillator chains from quantum algebras
Angel Ballesteros, Francisco J. Herranz
Completely integrable Hamiltonians defining classical mechanical systems of coupled oscillators are obtained from Poisson realizations of Heisenberg--Weyl, harmonic oscillator…
