Integrability of the \eta-deformed Neumann-Rosochatius model

Authors: Gleb Arutyunov, Martin Heinze, Daniel Medina-Rincon Preprint Number: UUITP-13/16 An integrable deformation of the well-known Neumann-Rosochatius system is studied by considering generalised bosonic spinning solutions on the \eta-deformed AdS_5 x S^5 background. For this integrable model we construct a 4x4 Lax representation and a set of integrals of motion that ensures its Liouville integrability. These integrals of motion correspond to the deformed analogues of the Neumann-Rosochatius integrals and generalise the previously found integrals for the \eta-deformed Neumann and AdS_5 x S^5_\eta geodesic systems. Finally, we briefly comment on consistent truncations of this model.
