Deformed strings in the Heisenberg model
R. Hagemans, J. -S. Caux
We investigate solutions to the Bethe equations for the isotropic S = 1/2 Heisenberg chain involving complex, string-like rapidity configurations of arbitrary length. Going beyond…

Dynamical structure factor at small q for the XXZ spin-1/2 chain
R. G. Pereira, J. Sirker, J. -S. Caux +4
We combine Bethe Ansatz and field theory methods to study the longitudinal dynamical structure factor S^{zz}(q,omega) for the anisotropic spin-1/2 chain in the gapless regime. Usin…

Boson decay and the dynamical structure factor for the XXZ chain at finite magnetic field
J. Sirker, R. G. Pereira, J. -S. Caux +4
We study the longitudinal dynamical structure factor for the anisotropic spin-1/2 (XXZ) chain at finite magnetic field using bosonization. The leading irrelevant oper…
