Boosting Nearest-Neighbour to Long-Range Integrable Spin Chains

Understand

We present an integrability-preserving recursion relation for the explicit construction of long-range spin chain Hamiltonians.

• These chains are generalizations of the Haldane-Shastry and Inozemtsev models and they play an important role in recent advances in string/gauge duality.
• The method is based on arbitrary nearest-neighbour integrable spin chains and it sheds light on the moduli space of deformation parameters.
• We also derive the closed chain asymptotic Bethe equations.
