Non-crystallographic reduction of generalized Calogero-Moser models
Andreas Fring, Christian Korff
We apply a recently introduced reduction procedure based on the embedding of non-crystallographic Coxeter groups into crystallographic ones to Calogero-Moser systems. For rational…
Affine Toda field theories related to Coxeter groups of non-crystallographic type
Andreas Fring, Christian Korff
We propose affine Toda field theories related to the non-crystallographic Coxeter groups H_2, H_3 and H_4. The classical mass spectrum, the classical three-point couplings and the…
A Q-Operator Identity for the Correlation Functions of the Infinite XXZ Spin-Chain
Christian Korff
An explicit construction for Q-operators of the finite XXZ spin-chain with twisted boundary conditions is presented. The massless and the massive regime is considered as well as th…
Exactly solvable potentials of Calogero type for q-deformed Coxeter groups
Andreas Fring, Christian Korff
We establish that by parameterizing the configuration space of a one-dimensional quantum system by polynomial invariants of q-deformed Coxeter groups it is possible to construct ex…
Loop symmetry of integrable vertex models at roots of unity
Christian Korff, Barry M. McCoy
It has been recently discovered in the context of the six vertex or XXZ model in the fundamental representation that new symmetries arise when the anisotropy parameter $(q+q^{-1})/…
Colours associated to non simply-laced Lie algebras and exact S-matrices
Christian Korff
A new set of exact scattering matrices in 1+1 dimensions is proposed by solving the bootstrap equations. Extending earlier constructions of colour valued scattering matrices this n…
