Fukui-Kawakami chains: spectrum and hidden -symmetry
Rob Klabbers, Antoine Lefebvre
Fukui and Kawakami showed that the trigonometric Haldane--Shastry (HS) spin chain can be deformed by introducing twisted boundary conditions. In this work we revisit the resulting…
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…
Regge spectroscopy of higher twist states in supersymmetric Yang-Mills theory
Rob Klabbers, Michelangelo Preti, István M. Szécsényi
We study a family of higher-twist Regge trajectories in supersymmetric Yang-Mills theory using the Quantum Spectral Curve. We explore the many-sheeted Riemann surfa…
The deformed Inozemtsev spin chain
Rob Klabbers, Jules Lamers
The Inozemtsev chain is an exactly solvable interpolation between the short-range Heisenberg and long-range Haldane-Shastry (HS) chains. In order to unlock its potential to study s…
Periodic solutions of the non-chiral intermediate Heisenberg ferromagnet equation described by elliptic spin Calogero-Moser dynamics
Bjorn K. Berntson, Rob Klabbers
We present a class of periodic solutions of the non-chiral intermediate Heisenberg ferromagnet (ncIHF) equation, which was recently introduced by the authors together with Langmann…
The non-chiral intermediate Heisenberg ferromagnet equation
Bjorn K. Berntson, Rob Klabbers, Edwin Langmann
We present and solve a soliton equation which we call the non-chiral intermediate Heisenberg ferromagnet (ncIHF) equation. This equation, which depends on a parameter , descri…
How coordinate Bethe ansatz works for Inozemtsev model
Rob Klabbers, Jules Lamers
Three decades ago, Inozemtsev found an isotropic long-range spin chain with elliptic pair potential that interpolates between the Heisenberg and Haldane-Shastry (HS) spin chains wh…
Multi-solitons of the half-wave maps equation and Calogero-Moser spin-pole dynamics
Bjorn K. Berntson, Rob Klabbers, Edwin Langmann
We consider the half-wave maps (HWM) equation which provides a continuum description of the classical Haldane-Shastry spin chain on the real line. We present exact multi-soliton so…
Thermodynamics of Inozemtsev's Elliptic Spin Chain
Rob Klabbers
We study the thermodynamic behaviour of Inozemtsev's long-range elliptic spin chain using the Bethe ansatz equations describing the spectrum of the model in the infinite-length lim…
