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…
How to calculate correlation functions of Heisenberg chains
Rob Hagemans, Jean-Sébastien Caux, Jean Michel Maillet
We describe a method for calculating dynamical spin-spin correlation functions in the finite isotropic and anisotropic antiferromagnetic Heisenberg models. Our method is able to pr…
The 4-spinon dynamical structure factor of the Heisenberg chain
J. -S. Caux, R. Hagemans
We compute the exact 4-spinon contribution to the zero-temperature dynamical structure factor of the spin-1/2 Heisenberg isotropic antiferromagnet in zero magnetic field, directly…
The dynamical spin structure factor for the anisotropic spin-1/2 Heisenberg chain
R. G. Pereira, J. Sirker, J. -S. Caux +4
The longitudinal spin structure factor for the XXZ-chain at small wave-vector q is obtained using Bethe Ansatz, field theory methods and the Density Matrix Renormalization Group. I…
