Norms, overlaps and Yangian descendants for the Haldane-Shastry spin chain
Yunfeng Jiang, Jules Lamers, Yuan Miao
The Haldane-Shastry spin chain is a prototypical integrable model with long-range interactions, notable for hosting quasiparticles with fractional statistics and serving as a discr…

Modular families of elliptic long-range spin chains from freezing
Rob Klabbers, Jules Lamers
We consider the construction of quantum-integrable spin chains with q-deformed long-range interactions by `freezing' integrable quantum many-body systems with spins. The input is a…

Landscapes of integrable long-range spin chains
Rob Klabbers, Jules Lamers
We clarify how the elliptic integrable spin chain recently found by Matushko and Zotov (MZ) relates to various other known long-range spin chains. The limit gives the ellip…
