Integrability of the eta-deformed Neumann-Rosochatius model

Understand

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.
