On Bethe strings in the two-particle sector of the closed SU(2)q invariant spin chain
A. Ilakovac, M. Kolanovic, S. Pallua +1
In this paper we investigate complex solutions of the Bethe equations in the two-particle sector both for arbitrary finite number of sites and for the thermodynamic limit . We find…

Violation of the string hypothesis and Heisenberg XXZ spin chain
A. Ilakovac, M. Kolanovic, S. Pallua +1
In this paper we count the numbers of real and complex solutions to Bethe constraints in the two particle sector of the XXZ model. We find exact number of exceptions to the string…

XXZ spin chain in transverse field as a regularization of the sine-Gordon model
Silvio Pallua, Predrag Prester
We consider here XXZ spin chain perturbed by the operator sigma^x (``in transverse field'') which is a lattice regularization of the sine-Gordon model. This can be shown using conf…
