Boosting Nearest-Neighbour to Long-Range Integrable Spin Chains
Till Bargheer, Niklas Beisert, Florian Loebbert
We present an integrability-preserving recursion relation for the explicit construction of long-range spin chain Hamiltonians. These chains are generalizations of the Haldane-Shast…

Quantum Stability for the Heisenberg Ferromagnet
Till Bargheer, Niklas Beisert, Nikolay Gromov
Highly spinning classical strings on RxS^3 are described by the Landau-Lifshitz model or equivalently by the Heisenberg ferromagnet in the thermodynamic limit. The spectrum of this…
